Answer:

294 square meters

Explanation:

The surface area of a certain pyramid is 54 square meters. Its volume is 648 cubic meters. If a similar pyramid has a volume of 8232 cubic meters, what is its surface area?

We solve the above question using Proportion

The surface area of a certain pyramid

= 54 square meters.

Volume of certain pyramid =

648 cubic meters.

Surface area of similar pyramid = x

Volume of similar pyramid = 8232 cubic meters.

Hence,

Surface area : Volume

= Surface area/ Volume

= 54 m²/648 m³ = x/8232 m³

Cross Multiply

54 × 8232 = 648 × x

x = 54 × 8232/648

x = 294 square meters
