Question

The adjoining figure is the figure of two pillars

mounted a squared pyramid on the top. Find the
total cost of tiling the pillars at the rate of
Rs 52 per square feet.​

Answer 1

`Rs\ 4,296`

Explanation:

step 1

Find out the lateral area of the pillars

we know that

The lateral area of a rectangular prism is equal to

`LA=PH`

where

P is the perimeter of the base

H is the height of the prism

Determine the perimeter of the base

`P=4(1)=4\ ft` ----> is a square base

`H=6\ ft`

The lateral area is equal to

`LA=4(6)=24\ ft^2`

Remember that the number of pillars is 2

so

`LA=2(24)=48\ ft^2`

step 2

Find the cost of tiling the pillars at the rate of Rs 52 per square feet

Multiply the lateral area of the two pillars by the rate

so

`48(52)=Rs\ 4,296`
