Answer:
Explanation:
Volume of a cuboid: l*w*h
1. 12*2*10= 240 cm 2. 14*14*14= 2,744 mm 3. 3*22*2= 132 cm 4. 2.3*8*11.2= 206.08 cm
Volume of a triangular prism: b*h
1. (3*6)/2= 9*10= 90 m 2. (10*11)/2= 55*15= 825 cm 3. (4*15)/2=30*30= 900 mm
4. (4.5*9.9)/2=22.275*12= 267.3 m
Volume of a cylinder: V=πr^2h
1. 3.14*5^2=78.54*10= 785.4 cm 2. 3.14*6^2=113.1*9= 1,017.88 cm
3. 3.14*4^2=12.57*20= 251.33 cm 4. 3.14*7.2^2=162.86*3.2= 521.15 cm
