Question

topic 5: volume of a cube
question 1 find the volume of the following cubes.
question 2

Explanation:

Step1: Recall the volume formula for a cube

The volume formula for a cube is \( V = s^3 \), where \( s \) is the side length of the cube.

Step2: Calculate the volume for each cube

• Cube A: \( s = 2m \), so \( V_A=2^3 = 2\times2\times2=8m^3 \)
• Cube B: \( s = 4m \), so \( V_B = 4^3=4\times4\times4 = 64m^3 \)
• Cube C: \( s = 5cm \), so \( V_C=5^3=5\times5\times5 = 125cm^3 \)
• Cube D: \( s = 7m \), so \( V_D=7^3=7\times7\times7 = 343m^3 \)
• Cube E: \( s = 9m \), so \( V_E=9^3=9\times9\times9 = 729m^3 \)
• Cube F: \( s = 6m \), so \( V_F=6^3=6\times6\times6 = 216m^3 \)

Answer:

• \( V_A = 8m^3 \)
• \( V_B = 64m^3 \)
• \( V_C = 125cm^3 \)
• \( V_D = 343m^3 \)
• \( V_E = 729m^3 \)
• \( V_F = 216m^3 \)
