1. 3.Answer the following questions carefully.1. Find the volume of a cube if one of its faces has an area of 9 cm².
Penjelasan dengan langkah-langkah:
arti dari soal:1. Carilah volume sebuah kubus jika salah satu mukanya memiliki luas 9 cm².
jawaban:luas salah satu sisi kubus = 9 cm²
panjang sisi kubus
= √luas sisi
= √9
= 3 cm
volume kubus
= s × s × s
= 3 × 3 × 3
= 9 × 3
= 27 cm³
kesimpulan:jadi volume kubus tersebut adalah 27 cm³
Jawaban
27 cm³
Penjelasan dengan langkah-langkah:
volume =S³
√9
=3
V=3×3×3
=27

5. The Length of a rectangular is three time the width of it.The area of the garden is 48m square.find the dimension of the garden
Jawab:
Penjelasan dengan langkah-langkah:
Misalkan Panjang = P dan Lebar = L
P = 3L
Area = 48 m²
Area = P×L = (3L)(L) = 3L²
⇒ 3L² = 48
⇒ L² = 16
⇒ L = 4 m (Tidak mungkin lebar negatif)
Diperoleh P = 3×4 = 12 m
Maka, dimensi kebun: Panjang = 12 m dan Lebar = 4 m
6. a square cardboard of side 1.2 m has a 10 cm wide border round the exterior of three of its sides. find the area of the border!
Jawab:
0.38cm2
Penjelasan dengan langkah-langkah:
(Ada 3 sisi)
Area rectangle 1 : 1.4 x 0.1 = 0.14
Area rectangle 2 : 1.2 x 0.1 = 0.12
Area rectangle 3 : 1.2 x 0.1 = 0.12
Jadi, hasilnya : 0.14+0.12+0.12 = 0.38
7. a netal cube has a volume of 125m3. it is to be painted on all it faces. find the total area of the faces that will be coated with paint.
V = l^3
125 = l^3
5 m = length
surface area = 6l^2
S.A = 6. 5^2
s.a = 6×25
s.a = 150 m^2
8. A cube has a total surface area of the six faces equal to 150 square feet. What is the volume of the cube? Tolong dijawab ya kak....
Penjelasan dengan langkah-langkah:
Total Surface area of a cube is made by 6 area of square.
We can find side of cube ( s ) with equation :
Total Surface area = 6 Square area
150ft² = 6 s²
150ft² / 6 = s²
25ft² = s²
5ft = s
Find the volume ( V ) :
Vcube = s³
Vcube = (5ft)³
Vcube = 125 ft³
∴ The volume of cube is 125 ft³
9. the area of a rectangle is equal to the area of a square whose sides have length 8 cm. if the width of the rectangle = 4cm , then find the length of the rectangle
Jawaban:
40 cm
Penjelasan dengan langkah-langkah:
sides have length 8 cm : panjang sisi 8 cm
width rectangle = 4 cm : lebar persegi panjang itu 4 cm
L = p × l ➡️ Bahasa Indonesia
l × w = l × l
l × 4 = 8 × 8
4l = 64
l = 64/4
l = 16 cm
Find the length : 2(l + w)
= 2(16 + 4)
= 2(20)
= 40 cm

16. if the area of small square is 1cm2,then the area of shaded region is....
jika luas kotak kecil adalah 1cm2, maka area yang diarsir adalah ....
PQ = √(2² + 4²)
PQ = √(4 + 16)
PQ = √20
PQ = 2√5 cm
L.persegi = PQ² = (2√5)² = 20 cm²
L.persegi kecil = 2² = 4 cm²
L.arsir = L.persegi - L.persegi kecil
L.arsir = 20 - 4
L.arsir = 16 cm²

19. 19. If the area of a rectangle of width 6 cm is same as the area of a square of side 12 cm, then the length of the rectangle is …
Jawaban:
24 cm
Penjelasan dengan langkah-langkah:
Luas persegi = sisi² = 12² = 144 cm²
Luas persegi panjang = Luas persegi = 144
Luas persegi panjang = lebar×panjang
144 = 6×panjang
panjang = 24 cm
20. Given that the length of a rectangle is three times of the width. If the area of the rectangle is 192 cm2, then a half of the perimeter of its rectangle is…cm
l = 3w
l.w = A
(3w).w = 192
[tex]3{w}^{2} = 192 \\ {w}^{2} = \frac{192}{3} [/tex]
[tex]w = \sqrt{ \frac{192}{3} } = \sqrt{64} = 8[/tex]
l=3(w) = 3(8) = 24
(1/2) p = (1/2) 2(l+w)
= l + w = 24+8 = 32 cm
