The answer for 1A is 300ft³ but I don't know the answer for 1b 1A. A water tank that is rectangular in shape is 15 feet long, 10 feet wide, and 6 feet deep. What is thevolume of the water tank?
1B. If we want to paint all sides of the water tank from 1A, what is the total surface area that needs to be covered?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
