Question

please help :/ Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number.


A. 208 m2; 188 m2

B. 136 m2; 188 m2

C. 136 m2; 240 m2

D. 208 m2; 240 m2

Answer 1

The surface area of a cuboid is given by = 2(length*breadth + length*height + breadth*height)

Lateral surface area of cuboid = 2*height*(length + width)

Now we substitute the values:

TSA = 2(lw + lh + wh)
L = 13 m
W = 4 m
H = 4 m

So, TSA = 2(13*4 + 13*4 + 4*4) = 2(52 + 52 + 16) = 240 square meters.

LSA = 2*h*(l + w)
LSA = 2*4*(13 + 4) = 8*(17) = 136 square meters.

I think it should be the third option.
