Question

Find the surface area of a composite figure round to the nearest tenth if necessary to units

Answer 1

The composite image is that of a cuboid and a triangular prism

For the cuboid, the surface area will be

A = LB + 2BH + 2LH

L = 1.8

B= 1.1

H= 0.8

A = 1.8X1.1 + 2 X 1.1 X 0.8 + 2 X 1.8 X 0.8

A = 1.98 + 1.76 +2.88

Area of cuboid = 6.62
