Find the surface area of a cube with a volume of 64cm3

Volume = L x W x H

Since it’s a cube and all lengths are the same it would be:

Length of side = 3(square root symbol) 64

Length of side = 4cm

Surface area of a cube = L^2 x 6

Surface area = 4^2 x 6

Surface area = 96cm^2

How did you get 3 and 4

It was 64^3

For example : the square root of 100 is 10 because 10 x 10 = 100

But when you do volume there’s 3 sides involved: length x width x height

The sides of a square have all the same length so in a cube the length of the side length, width and height will all be the same right? Now there’s a button on your calculator that lets you square root but for 3 numbers. For example 3^(square root symbol) 8 = 2

Bc 2 x 2 x 2 = 8

Now understand why I did that?
