Please help i need it quick also plz show work

1: 180 in³

2: 75.36 in³

3: 255.36 in³

Step-by-step explanation:

To find the volume of the rectangular prism, you multiply length, width, and height.

v = 5 x 12 x 3

v = 60 x 3

v = 180 in cubed

To find the volume of the cylinder, you multiply pi (3.14) by the radius (3) by the height (8).

v = (3.14 x 3) x 8

v = 9.42 x 8

v = 75.36 in cubed

To find the volume of the entire figure, you add the volume of the rectangular prism and the cylinder together

v = 180 + 75.36

v = 255.36

0.50 , 0.75
