Answer:

240cm³

Step-by-step explanation:

To find our answer we will multiply the volume, width, and height.

4 · 20 · 3 = 240. Therefore, 240cm³ is our answer.

Have a good day!

Let's calculate its volume ~

Volume of a rectangular prism is :

$\qquad \sf \dashrightarrow \:v = l \cdot w\cdot h$

$\qquad \sf \dashrightarrow \:v = 20 \cdot 4\cdot 3$

$\qquad \sf \dashrightarrow \:v = 240 \: \: cm {}^{3}$

Which postulate or theorem can be used to

sveticcg [70]

Answer:

AA Similarity Postulate

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

step 1

Verify the proportion of the corresponding sides

$\frac{PS}{PQ}=\frac{PT}{PR}$

substitute

$\frac{45}{20}=\frac{36}{16}$

$2.25=2.25$ ----> is true

Corresponding sides are proportional

Triangle PQR is similar to Triangle PST

That means

Corresponding angles must be congruent

side QR is parallel side ST

and

$m\angle PQR=m\angle PST$ ----> by corresponding angles

$m\angle PRQ=m\angle PTS$ --> by corresponding angles

PQR is similar to PST by AA Similarity Postulate
