Question

The net of a composite space figure is shown below.
a. What figures make up the composite space figure?
b. What is the surface area of the composite space figure? Round your answer to the nearest square centimeter

Answer 1

1. A) The figures in the composition space figure are rectangles, triangles and a hexagon.

B) 1 hexagon =
a= 3sqrt3/2(4)^2
a= 3sqrt3/2(16)
a=41.57 cm.

6 triangles = a=1/2(4)(5)
a=1/2(20)
a=10 cm.
= 10 x 6
= 60 cm.
60 cm. is the area of all 6 triangles.

6 rectangles =
a=l*w
a= 6*4
a=24 cm.
a = 24*6
= 144 cm.
144 cm. is the area of all the rectangles.

S.A = 144+60 +41.57
S.A =245.57 cm.^2

Answer 2

is that the correct answer?

Answer 3

yes, but they want the answer rounded to the nearest whole number.
