The lid of a jewelry box is in the shape of a triangular prism. The lid has a height of 12 inches. The triangular base of the li
d has a base of 31 inches and a height of 4 inches.. What is the volume of the lid to the nearest tenth?
1 answer:
Answer:
Volume of the lid is 740in³
Step-by-step explanation:
Kindly find attached rough sketch of the lid
The volume of a triangular prism is expressed as
V= 1/2(a*c*h)
Where
a,is the height of triangular base = 4in
c, triangular base = 31in
h, height of the lid = 12in
Substituting our given data we have
V= 1/2(4*31*12)
V= 1488/2=744in³
To the nearest tenth is 740in³
