Complete Question

Angela makes a pillow in the shape of a wedge to use for watching TV. The pillow is filled with 0.35 m³ of fluffy

material. The base is 0.5m² and the height is 1m.

What is the length of the pillow?

Give an exact answer (do not round).

Answer:

1.4m

Step-by-step explanation:

A wedge comes in the shape of a Triangular prism. Hence,

Volume of a wedge(Triangular prism) = 1/2 × B × H × L

b = 0.5m

h = 1 m

l = ??

Volume of a wedge = 0.35m³

0.35 = 1/2 × 0.5 × 1 × L

0.35 = 0.25 × L

L = 0.35/0.25

L = 1.4m
