. The volume of a cube is 1728 . Find its edge and total surface area
emmasim [6.3K]

Answer:

Edge = 12

Total Surface Area = 72

Step-by-step explanation:

Volume of the cube = 1728

Length of the edge = \sqrt[3]{1728}  = 12

We know that

TSA (Total Surface Area) = 6 {a}^{2}

where a = length of edge of cube

So,

TSA of cube = 6 \times 12 = 72

The problem is asking for the height of the fluid using the following information:

Volume of fluid
=
V
=
36

Radius of new cylinder
=
r
=
