Answer: 1078.9 cm^3 is the volume of metal used in making axe.
Step-by-step explanation:
volume ( surface area * 2 ) of rectangular wedge= 2( 18.3 * 12)
= 439.2 cm^3
volume of cylindrical part except hole = v =4/3 * π *r^3
=904.78 cm^3 (taking radius as 6 cm)
v =4/3 * π *r^3
=268.08 cm^3( taking radius as 4 cm)
=>904.08 cm^3 - 268.08 cm^3 = 636.7 cm^3
total volume of metal used = 636.7 cm^3 + 439.2 cm ^3
=1078.9 cm^3
