Raj builds a side table in the shape of a cube. Each edge of the cube measures 21 inches. Raj wants to cover the top and four sides of the table with ceramic tiles. Each tile has an edge length of 3 inches. How many tiles will he need? Pls answer fast​

2000/25 = 80 tiles

Step-by-step explanation:

Date: s=20

equation of surface area of a cube prism: surface area = 6s*2

the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2

subtitute values: surface area = 5(20)*2

= 5(400)

surface area = 2000

area of 2 tile is 5*2 = 25 square inches

2000/25 = 80 tiles

the area of ​​the surface of the rectangular prism here is 250 cm2, which is the surface of the shading
