Question

Find the total area of the solid figure.
90 sq. ft.
126 sq.ft
150 sq.ft

Answer 1

90 sq. ft.

Explanation:

The formula you need to use is length*width*height. If you plug the numbers given into the equation, you get 5*3*6. Multiply this for the answer.

Answer 2

Answer: The correct option is (B) 126 sq. feet.

Step-by-step explanation: We are given to find the total area of the solid figure.

We can see that the given solid figure is a cuboid.

The total area of a cuboid with length l units, breadth b units and height w units is given by

`A=2(lb+bh+hl).`

For the given cuboid, we have

length, l = 5 feet,

breadth, b = 3 feet and

height, h = 6 feet.

Therefore, the total area of the given cuboid will be

`A=2(5* 3+3*6+6* 5)=2(15+18+30)=2*63=126~\textup{sq. feet}.`

Thus, the total area of teh solid figure is 126 sq. feet.

Option (B) is CORRECT.
