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
