Answer 1

Answer:

see explanation

Step-by-step explanation:

(a)

The shaded figure is a trapezium with area (A)

A = 0.5 h(a + b)

where h is the perpendicular height and a, b the parallel sides, thus

A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²

(b)

The volume (V) of the prism is calculated as

V = area of end face × depth

  = 110 × 3 = 330 cm³
