Question

the solid below is made from cubes. find its volume.

Explanation:

Step1: Identify cube edge length

Edge length of 1 cube: $l = 1\ \text{m}$

Step2: Calculate single cube volume

Volume of 1 cube: $V_1 = l^3 = 1^3 = 1\ \text{m}^3$

Step3: Count total number of cubes

Number of cubes: $5 \times 2 \times 3 = 30$

Step4: Compute total solid volume

Total volume: $V = 30 \times V_1 = 30 \times 1 = 30\ \text{m}^3$

Answer:

30
