Answer 1

102cm³

Explanation:

Imagine the shape as two rectangular prisms, a small one on top of a bigger one. Find their volumes individually, and then add them together:

Small rectangular prism

Volume=length*width*depth

=2*3*(7-5)

=6*2

=12cm³

Bigger rectangular prism

Volume=length*width*depth

=6*3*5

=6*15

=90cm³

12+90=102cm³
