area of a cube of side 20 cm.​

Answer 1

side of cube =20cm

lateral surface area of cube= 4 a sq

=4(20) sq

=1600 cm sq

total surface area of cube =6 a sq

=6(20) sq

Answer 2

Answer:

Total Surface area = 2400cm²

Lateral surface area = 1600cm²

Step-by-step explanation:

Total surface area of cube

= 6a²

= 6 × 20²

= 6 × 20 × 20

= 2400 cm²

Lateral surface area of cube
