gtnhenbr [62]

Answer:

The question to your answer is:            V = 300 u³

Step-by-step explanation:

Rectangular prism        900 u³   base = 5 u  height = 10 u

Rectangular pyramid  = ?

Rectangular prism = V = large x height x width

                                 900 = large x 10 x 5

                                 900 = large x 50

                                 900 / 50 = large

                                18 = large

Rectangular pyramid = V = 1/3 L x w x h

                                     V = (1/3) 18 x 5 x 10

                                     V = 300 u³
