The base of a one litre carton of milk is 8cms x 8cms. What must be its minimum height?
17,6 cm
64 cm
16 cm
16,7 cm
To find the minimum height of the carton of milk, we need to calculate its volume and then divide by the base area.
The base area of the carton is 8cm x 8cm = 64cm^2.
Since the volume of the carton is 1 liter and there are 1000 cm^3 in a liter, the volume is 1000 cm^3.
To find the height, we divide the volume by the base area:
1000 cm^3 / 64 cm^2 = 15.625 cm.
Since the height cannot be a fraction, we round up to the nearest whole number.
The minimum height of the carton of milk must be 16 cm.
