Using the distributive property , 4*9+4*7 or 36+28
This is the concept of volumes of solid figures;
volume=length*width*height
the dimensions of our figure is:
length=15 1/2 in=31/2 in
width=10 1/4 in=41/4 in
height= 12 in
thus the volume will be:
volume=(31/2*41/4*12)
volume=1906 1/2 in^3
the answer is 1906 1/2 in^3
