Question

The surface area of a cube is
$18 \times \frac{3}{8}$
Find its volume.​

Answer 1

Step-by-step explanation:

where S = surface area (in units squared), V = volume (in units cubed), and l = the length of one side of the cube. ... Notice that for any increase, x * l or x * r, in length or radius, the increase in surface area is x squared (x2) and the increase in volume is x cubed (x3).

so

x^2=18×3/8

x^2=54/8

x^2=27/4

x=√27/4

x=3√3/2

so volume is x^3

(3√3/2)^3

54√3/8

mark as brilliant and take thanks for all question of

Answer 2

Answer:

42.5√6.5

Step-by-step explanation:

TSA=39m^2

TSA=6a^2

6a^2=39

a=√6.5

volume=a^3

volume=42.5√6.5
