Answer:
volume=240
height=9.6
width=3
height=2.5
length=7
Explanation:
the formula for colume of prism is area of teh base times the heigth so
the first one is 6*5(8)=240
the next one you wouold solve for height so 4.5 tims 5 times x(height)= 2.6
height equals 9.6
the next one solve for width so 3*x*3=27
width is 3
the next one you solve for height so 2.5*8.4*x=52.5
the height is 2.5
the last one you solve for length so x*7*7=343
length equals 7
