Question

Calculate the surface area of this box.

Answer 1

`A=40cm^(3)`

Explanation:

Formula to find the surface area of a rectangular prism:

`A=2(wl+hl+hw)`

`(w=weight, l=length, h=height)`

`A=2((2)(4)+(2)(4)+(2)(2))`

`A=2((2)(4))+2((2)(4))+2((2)(2))`

`A=16+16+8`

`A=40cm^(3)`

hope this helps :)

Answer 2

36 cm^2

Explanation:

S.A. = 2 (lw + wh + lh)

S.A. = 2 ((4)(2) + (2)(2) + (4)(2))

S.A. = 2 (8 + 4 + 6)

S.A. = 2 (18)

S.A. = 36
