What is the volume of a room 84 feet long, 48 feet wide and 28 ft high

112,896 ft. cubed

Step-by-step explanation:

Volume is length times width times height. We have all three measures. 84*48*28 equals 112,896. Becuase we are solving for volume, the unit of measure has to be cubed (to the square root of 3). Therefore, the volume of the room is 112,896 ft. cubed.

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

0.32
