Answer:
782.5inch³
Step-by-step explanation:
<u>The question is on volume of a prism and that of a cylinder</u>
<u>Finding the volume of the prism</u>
V=Bh where B is the base area and h is the height
Base area=14"×14"=196 inch²
height =8"
v=196×8= 1568 in³
<u>Finding volume of the cylinder</u>
v=r²h where r is the radius of cylinder and h is the height of cylinder
r=10/2=5 inches and h=10 inches
v=3.142×5×5×10=785.5inch³
<u>The difference in volume</u>
Difference in volume=1568-785.5=782.5inch³
First we r gonna find the other leg
a^2 + b^2 = c^2
32^2 + b^2 = 40^2
1024 + b^2 = 1600
b^2 = 1600 - 1024
b^2 = 576
b = sqrt 576
b = 24
perimeter is : a + b + c
p = 32 + 24 + 40 = 96 m <===

(y+5)(y+6+5) = 187
y2+16y+55 = 187
y2 +16y - 132 =0
y = 6 or -22(rejected)
