Question

If a pyramid is oblique rather than right, what is true about finding the surface area and volume?

• A. Surface area is done differently than for a right pyramid
  Volume is done the same way as for a right pyramid
• B. Surface area is done the same way as for a right pyramid
  Volume is done differently than for a right pyramid
• C. Surface area is done differently than for a right pyramid
  Volume is done differently than for a right pyramid
• D. Surface area is done the same way as for a right pyramid
  Volume is done the same way as for a right pyramid

Answer 1

The correct option is A Surface area is done differently than for a right pyramid

Volume is done the same way as for a right pyramid
$\left(i\right)$ Oblique pyramid is a pyramid with an apex that is not aligned above the center of the base.

Whereas, right pyramid is a pyramid where an apex is aligned above the center of the base.

$\left(ii\right)$ Since, volume is the quantity of three-dimensional space enclosed by a closed surface.

So, the volume of both the pyramids remain same as the area inside the shape is same.

$\left(iii\right)$ Since, surface area is the amount of area outside the $3$-dimensional shape.

Thus, the surface area will be calculated in a different way.

Hence, option A is correct.
