Question

Calculate the surface area of this box.

Answer 1

Answer:

$A=40cm^{3}$

Step-by-step 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

Answer:

36 cm^2

Step-by-step 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
