Solution:
Given that,
Rectangular prism has:
length = 13.2 feet
width = 6 feet
height = 8 feet
Find the lateral surface area of prism:
[tex]\text{Lateral surface area } = 2(length + width) \times height\\\\\text{Lateral surface area } = 2(13.2 + 6) \times 8\\\\\text{Lateral surface area } = 2(19.2) \times 8\\\\\text{Lateral surface area } = 38.4 \times 8\\\\\text{Lateral surface area } = 307.2\ ft^2[/tex]
Thus the lateral surface area of prism is 307.2 square feet
Martina's estimation that lateral surface area is about 304 square feet is quite near to the calculated value which means that her estimation should have been really reasonable.
