The surface areas of two similar rectangular prisms are 361 m2 and 441 m2. What is the scale factor of the larger prism to the smaller prism?

Option C:

The scale factor of the larger prism to the smaller prism is .

Solution:

Two rectangular prisms are similar.

Surface area of the smaller prism = 361 cm²

Surface area of the larger prism = 441 cm²

Scale factor of larger prism to smaller prism

Both square and square roots are cancelled, we get

The scale factor of the larger prism to the smaller prism is .

Hence Option C is the correct answer.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
