BMST - Basic Math and Science Geometric Area and Volume Questions and Answers 4

Question 1

A rectangular swimming pool is 25 m long, 10 m wide, and 2 m deep. How many cubic meters of water does it hold?

Accepted Answer

500 m³

Answer

Volume = length × width × depth = 25 × 10 × 2 = 500 m³.

Question 2

What is the circumference of a circle with a diameter of 14 inches? (Use π ≈ 3.14)

Accepted Answer

43.96 inches

Answer

Circumference = π × d = 3.14 × 14 = 43.96 inches.

Question 3

A parallelogram has a base of 9 cm and a height of 7 cm. What is its area?

Accepted Answer

63 cm²

Answer

Area of a parallelogram = base × height = 9 × 7 = 63 cm².

Question 4

A box is 8 inches long, 5 inches wide, and 3 inches tall. What is its total surface area?

Accepted Answer

158 in²

Answer

SA = 2(lw + lh + wh) = 2(40 + 24 + 15) = 2 × 79 = 158 in².

Question 5

The radius of a circle is doubled. How does its area change?

Accepted Answer

It quadruples

Answer

Since A = πr², doubling r gives π(2r)² = 4πr², so the area becomes 4 times larger.
