Question

Raj builds a side table in the shape of a cube. Each edge of the cube

measures 20 inches. Raj wants to cover the top and four sides of the table
with ceramic tiles. Each tile has an edge length of 5 inches. How many
tiles will he need?

Answer 1

Answer: 80 tiles

Explanation:

Given that the Raj wants to cover the top and four sides of the table, we determine the summation of the areas. That is,

A (total) = 5 x (20 in)² = 2000 in²

Then, the area of each ceramic tile is equal to,

A (ceramic tile) = (5 in)² = 25 in²

Dividing the total area by the area of the ceramic tile will give us an answer of,

n = 2000 in² / 25 in² 80

Thus, Raj will be needing 80 tiles.
