Can someone help me with this pls?

Pavlova-9 [17]

Answer:

1176 $cm^{3}$

Step-by-step explanation:

First, calculate the volume as if it was a full rectangle.

Volume formula:

length x width x height

16 x 6 x 21 = 2016 $cm^{3}$ (this is the volume if this was a full rectangle)

Now to calculate the size of the missing part we do the same thing

10 x 6 x 14 = 840 $cm^{3}$

To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle

2016 - 840 = 1176 $cm^{3}$

I hope this helped :-)
