Full Question
Angela makes a wedge-shaped pillow to use for watching TV. The pillow is filled with 0.35 m³ of fluffy
subject. The base is 0.5m² and the height is 1m.
What is the length of the pillow?
Give an accurate (not accurate) answer.
1.4m
Step by step explanation:
A wedge comes in the shape of a Triangular prism. Hence,
Wedge volume (Triangular prism) = 1/2 × B × H × L.
b = 0.5m
h = 1 m
l = ??
Wedge volume = 0.35m³
0.35 = 1/2 × 0.5 × 1 × L.
0.35 = 0.25 × L.
L = 0.35 / 0.25
L = 1.4m
