Penelope builds a side table in the shape of a cube. Each edge of the cube measures 20 inches. Penelope 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 be needed?

OpenStudy (misty1212):

HI!!

OpenStudy (misty1212):

so each tile is \(25^2\) inches right ?

OpenStudy (misty1212):

and each side of the cube measures \(20\times 20=400^2\) inches, and you have four of them for a total of \(1600^2\) inches divdie

OpenStudy (misty1212):
