A right prism has a square base with side 10 cm. The height of the prism is 12 cm. What is the total surface area?
Show answer & explanation
Correct answer: C
Explanation
Base side = 10 cm, Height = 12 cm
According to the formula: Total Surface Area = 2a² + 4ah
= 2(10²) + 4(10 × 12)
= 2 × 100 + 4 × 120
= 200 + 480 = 680 cm²
