Question

Find the lateral surface area and total surface area of a cube whose side is of
length:
a. 8 cm
d. 2500 cm
b. 11.5 cm
c. 10.4 m​

Answer 1

Step-by-step explanation:

TSA of cube = 6 × (side)^2

LSA of cube = 4 × (side)^2

a. TSA = 6×8^2 = 6 × 64 = 384 sq. cm

LSA = 4×8^2 = 4 × 64 = 256 sq. cm

b. TSA = 6× 2500^2 = 6 × 6250000 = 37500000 sq.cm

LSA = 4× 2500^2 = 4×6250000 = 25000000 sq. cm

c. TSA = 6× 11.5^2 = 6 × 132.25 = 793.5 sq. cm

LSA = 4× 11.5^2 = 4 × 132.25 = 529 sq. cm
