Answer:
Length = 10 cm
Width = 10 cm
Height = 12 cm
Step-by-step explanation:
Cost of a cardboard with a square base and top = 0.3 cents per cm²
0.3 cents = $0.003 (0.3/100)
Total cost for material = $3.6
The volume of the box = $3.6/$0.003 = 1,200cm³
The formula for volume = length × width × height.
Since the base and top are square, the length and width must have equal sizes.
Let us assume that
length = 10cm
width = 10cm
these will give an area of 100cm².
Volume = length * width * height
= Area * height
= 10 * 10 * height
= 100cm² * height
Therefore, the height will be the volume divided by area
= 1,200cm³/100cm²
= 12cm
Volume = 10 * 10 * 12
= 1,200cm³
