Length of a rectangular prism is increased by factor of 1.5. The width is doubled and height is tripled. What is the new volume?
Alenkasestr [34]

The new volume is Nine time the original volume

Step-by-step explanation:

Let the length be 'l'

Let the height be 'h'

Let the width be 'w'

Volume of a rectangular prism= l x w x h

New length = 1.5l

New width = 2w

New height= 3h

New volume= (1.5l) x (2w) x (3h)

= 9 (l x w x h)

New volume= 9 ( original volume)

The new volume is 9 time the original volume

If 1" = 2.5' then how many feet is 3.75"=
Gnesinka [82]
1" = 2.5'
2.5'(3.75") = 9.375'

3.75" = 9.375'

For every inch is 2.5ft
1 - 2.5 ft
2 - 5 ft
3 - 7.5 ft 
.75' - 0.625 ft
7.5' + 0.625' = 9.375"
