Layla wants to build a wooden box with a volume of 450 cubic centimeters.

She started with a width of 10 cm and a height of 3 cm.

How long should Layla make the box?

length = 15 cm

Step-by-step explanation:

The volume of the box = length * width * height

Given: volume = 450 cm³, width = 10 cm and height = 3 cm

∴ 450 = length * 10 * 3

∴ 450 = 30 * length

∴ length = 450/30 = 15 cm

so, the box will be 15 cm long.
