Question

Suppose you have one pyramid with a base that is 10 meters long and 10 meters wide with a slant that is 15 meters. Now, if the length of the base is

Answer 1

The difference between area of pyramids is 125 sq.m.

Explanation:

Length of base = 10m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid =
`(1)/(2) * 10 * 15+(1)/(2) * 10 * 15+(1)/(2) * 10 * 15+(1)/(2) * 10 * 15+10 * 10`

Area of pyramid = 400 sq.m.

Now the length of base is increased to 15

Length of base = 15m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid =
`(1)/(2) * 15 * 15+(1)/(2) * 15 * 15+(1)/(2) * 10 * 15+(1)/(2) * 10 * 15+10 * 10`

Area of new pyramid = 525 sq.m.

Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.

Hence The difference between area of pyramids is 125 sq.m.
