Answer:
102cm³
Step-by-step 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
