Answer 1

if i had to say i would say B. 15 sq cm

Explanation:

Answer 2

Option A.
`37.5\ cm^(2)`

Explanation:

we know that

The surface area of a cube is equal to

`SA=6(b)^(2)`

where

b is the length side of the cube

In this problem we have

`b=2.5\ cm`

substitute the value in the formula

`SA=6(2.5)^(2)=37.5\ cm^(2)`
