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
