Question

1. Find the total surface area of a solid cube of volume 64 cm^3.​

Answer 1

Answer:

Since the volume is 64cm^3 the side of cube is a=cubic root of 64=4 cm. The total surface area S=6a^2=6(4)^2=6(16)=96 cm^2.

Answer 2

Step-by-step explanation:

Let side of cube be 'a'

given ,

volume =a^3 =64cm^3 so , a =4

total surface area = 6a^2

" =6×4^2

Hence ,

total surface area = 96cm ^2
