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
