Question

Find the surface area of the cube whose dimensions are (a) 7 cm, (b) 10 m.

Answer 1

Given:

1. Cube with side = 7 cm
2. Cube with side = 10 m

Step-wise calculation:

Formula: Total surface area of a cube = 6 × (side)².

a. Side = 7 cm

SA = 6 × (7 cm)²

SA = 6 × 49 cm²

SA = 294 cm²

b. Side = 10 m

SA = 6 × (10 m)²

SA = 6 × 100 m²

SA = 600 m²

1. Total surface area = 294 cm².
2. Total surface area = 600 m².
