Question

what is the total surface area of a cube whose edge is 1.5 cm

Answer 1

Answer:

Step-by-step explanation:

Volume=a^3

i.e 3.38cm^3

and total surface area

SA = 6 × a2

SA = 6 × (1/2)2

SA = 6 × (1/2)2SA = 6 × 1/2 × 1/2

SA = 6 × (1/2)2SA = 6 × 1/2 × 1/2SA = 6 × 1/4

SA = 6 × (1/2)2SA = 6 × 1/2 × 1/2SA = 6 × 1/4SA = 1.5 cm2
