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

Answer:

$Rs\ 4,296$

Step-by-step 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

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