Question

Next problem math please

Answer 1

As you can see, both blocks have the same depth (5 cm)

So for the first block (left):

$V_1=length*width*depth\\~\\~\\V=8*3*5=120~~cm^3$


For the second block (right):

$V_2=5*6*2=60~~cm^3$


Add them up, you get:
$V_{total}=V_1+V_2=120+60=180~~cm^3$

Done!! :)
