A right prism has a trapezoidal base with parallel sides 6 cm and 10 cm, height of trapezoid 4 cm, and prism height 12 cm. Find the volume.
Show answer & explanation
Correct answer: A
Explanation
Has been given :
Parallel sides of trapezium = 6 cm, 10 cm
Height of trapezium = 4 cm
Height of prism = 12 cm
According to the formula:
Area of trapezium = (1/2) × (a + b) × h
Volume of prism = base area × height
Base area= (1/2) × (6 + 10) × 4
= (1/2) × 16 × 4
= 32 cm²
Volume= 32 × 12= 384 cm³
