Answer :
Final answer:
To calculate the amount of sand needed for Maija's sandbox, multiply the length, width, and height to get the volume. For her 2 feet by 2 feet sandbox with a desired sand depth of 1.55 feet, she needs to order 6.2 cubic feet of sand.
Explanation:
Maija is constructing a square sandbox which has sides of 2 feet in length and desires a sand depth of 1.55 feet. To find out how much sand Maija should order, we need to calculate the volume of the sand that will fill the sandbox. The formula for the volume of a cube or rectangular solid is volume = length imes width imes height.
In Maija's case, the sandbox has all sides of equal length since it is a square, so the length and the width are both 2 feet. Therefore, the volume of the sandbox would be:
Volume = length imes width imes height
Volume = 2 ft imes 2 ft imes 1.55 ft
Volume = 4 ft2 imes 1.55 ft
Volume = 6.2 ft3
Hence, Maija should order 6.2 cubic feet of sand to achieve the desired depth of 1.55 feet in the sandbox.
