Raj builds a side table in the shape of a cube. Each edge of the cube measures 30 inches. Raj wants to cover the top and four sides of the table with ceramic tiles. Each tile has an edge length of 6 inches. How many tiles will he need?

125

Step-by-step explanation:

Find the surface area of the table that Raj wants to cover.

Since the side table is a cube each side is identical.

Step 2:

Raj wants to cover 5 sides of the cube. Therefore the total surface area to be covered is 5 · 30 · 30 = 4,500 square inches.

Step 3:

Find the surface area of each tile.

The surface area of each tile is 6 · 6 = 36 square inches.

Step 4:

Find the number of tiles needed to cover the table.

4,500 square inches

36 square inches per tile

= 125 tiles

Raj will need 125 tiles to cover the table.
