The volume of a cubical block is 42.875 m3. What is its surface area? Express your answer as a decimal.

Answer 1

Step-by-step explanation:

a3=42.875m3

a=3✓42.875

a=3.5 m

TSA of Cube = 6a2

= 6x(3.5) 2

= 6x12.25

= 73.5m2

Answer 2

Answer:

Volume of cubical block=42.875m3

${a}^{3} = 42.875$

a=3.5m

Surface area=

$6 {a}^{2}$

=6×3.5×3.5=73.5m^2
