Answer:
Surface area of 5 sides = 51.2 cm²
Step-by-step explanation:
Given:
Side of cube = 3.2 cm
Find:
Surface area of 5 sides
Computation:
Surface area of 5 sides = Surface area of cube - Surface area 1 side
Surface area of 5 sides = 6a² - a²
Surface area of 5 sides = 6(3.2)² - (3.2)²
Surface area of 5 sides = 6(10.24) - 10.24
Surface area of 5 sides = 6a² - a²
Surface area of 5 sides = 61.44 - 10.24
Surface area of 5 sides = 51.2 cm²
