Answer:
use the formula : v=lwh
v= 24l× 62.6w×38 .1 h
v= 24cm× 62.6cm× 38.1 cm
v= 57, 241.44cm
2. v= 461.81cm³

1. Vrectangle= 57241.44 cm³
2. Vcone= 147[tex]\pi[/tex] cm³ or 461.81 cm³
3. Vrectangle= 576 cm³
Step-by-step explanation:
For number 1:
Given: 24cm long, 62.6cm wide, and 38.1cm deep
Required: Vrectangle= ?
Solution:
The volume of rectangle is given by
Vrectangle= L x W x H
Substituting the given in the formula,
Vrectangle= 24 x 62.6 x 38.1
Vrectangle= 57241.44 cm³
For number 2,
Given: 9cm height, and 7cm radius base
Required: Vcone= ?
The volume of the cone is given by
Vcone= [tex]\frac{1}{3}[/tex] ([tex]\pi[/tex]) (r²) (h)
Vcone= [tex]\frac{1}{3}[/tex] ([tex]\pi[/tex]) (7²) (9)
Vcone= 147[tex]\pi[/tex] cm³ ≈ 461.81 cm³
For number 3:
Given: 12cm length, 6cm width, and 8cm height
Vrectangle= 12 x 6 x 8
Vrectangle= 576 cm³
