Question

Can someone help me with this?

Answer 1

Given side of cube = 3.4 inches

Considering 3.4 as 'a'

So,

`{a}^(3) = volume`

`= > 3.4 * 3.4 * 3.4 = volume`

`= > 39.304in^(3)`

Now,

`6 {a}^(2) =`surface area

`= > 6 * (3.4)^(2) =`surface area

`= > 69.36in^(2)`

Therefore,

Volume of cube = 39.304 in^3

Surface area of cube = 69.36 in^2

Answer 2

cube volume = edge³

= 3.4³

= 39.304 in³

Surface area = 6edge²

= 6 × 3.4²

=69.36 in²
