Answer: 88 inches ^2
Step-by-step explanation:
Surface area of a rectangular prism is calculated by A=2(wl+hl+hw)
where w is width given as 10inches
h is the height given as 2inches
l is the length given as 2inches
wl = width x length = 10 x 2 = 20inches
hl = height x length= 2 x 2 = 4inches
hw= height x width = 2 x 10 = 20inches
Slot the values into the formula
A= 2 (20 + 4 + 20)
A= 2 (44)
A = 2 x 44
A = 88inches^2
