A construction worker needs to determine the volume of a sandplle in a construction yard, as shown. A line along the surface of the sandpile from the ground to the top of the sandpile makes a 40° angle with the ground at point R.
• The length of the slant side of the sandpile, RT, from the ground to the top of the sandplle Is 20 meters.

What is the volume of the sandpile, to the nearest cubic meter? Show your work and explain how you determined your answer.
Enter your answer, your work, and your explanation in the box provided.

the answer will be the last one

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
