Question

the perimeter of one face of a cube is 20 cm find the total area of of the 6 faces the volume of the cube

Answer 1

Answer:

Total surface area = 150 cm² ; Volume = 125 cm³

Step-by-step explanation:

Perimeter of one face = 20 cm

Perimeter = 4 x Length

4 x Length = 20

Length = 20 ÷ 4 = 5 cm

Find the total surface area:

Area of 1 face = 5 x 5 = 25 cm²

Area of 6 faces = 25 x 6 = 150 cm²

Find the volume:

Volume = Area x Height

Volume = 25 x 5 = 125 cm³

Answer: Total surface area = 150 cm² ; Volume = 125 cm³
