Layla wants to build a wooden box with a volume of 45 cubic centimeters. She started with a width of 3 cm and a height of 3 cm.How long should Layla make the box?

Respuesta :

Volume = length x width x height

45 cubic centimeters = length x 3cm x 3cm 
45 cubic centimeters = length x 9cm^2
(45 cubic centimeters) / 9cm^2 = length 
5 cm = length
