Question

Every surface of the block shown will be painted, except for one of the bases. How many square units will be

Answer 1

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
