Step-by-step explanation:

volume of rectangular prism = lbh ( l is length, b is breadth, h is height )

Here l = 11, b = 8 , h = 4

V = 11 × 8 × 4 = 352 ft³

volume of triangular prism = Al ( A is area of triangular end and l is its length )

A = bh ( b is base and h is height )

Here b = 8, h = 4 and l = 7

A = × 8 × 4 = 4 × 4 = 16 ft² , then

V = 16 × 7 = 112 ft³

volume of composite figure = 352 + 112 = 464 ft³
