Question

Dmitri wants to cover the top and sides of this box with glass tiles that are 1 cm square. How many tiles will he need?

Answer 1

Answer is 1046 tiles at 1 cm size

Step by step

We need to find surface area of 5 sides and add them together (no bottom was mentioned)

1 Top = 26 x 15 = 390
2 Short sides = 2(15 x 8) = 240
2 Long sides = 2(26 x 8) = 416

390 + 240 + 416 = 1046 sq cm

Divide your sq cm by size of tile

1046 / 1 = 1046 tiles

This is assuming no grout gap between tiles
