e3T.A.54V27

Step by step solution

01

Step 1. Given information.

The length of the edge of the cube is 3. That is,e=3 .

02

Step 2. Write the concept.

The total area of the cube is given by:

T.A.=6e2

The volume of rectangle is given by:

V=e3

03

Step 3. Determine the value.

Now, substitute all the given values in the formula.

Then, the total area is given by:

T.A.=6e2=6(3)2=6(9)=54鈥夆赌塽苍颈迟2

And the volume is

V=e3=(3)3=3脳3脳3=27鈥夆赌塽苍颈迟3
