Final answer:
To determine the number of bags of sand Sheldon needs to purchase to fill the sandbox, we first need to calculate the volume of the sandbox. "4 bags" of sand will he need to purchase to fill the sandbox. So, the correct option is "c" " 4 bags".
Step-by-step explanation:
Certainly! Let's proceed with the calculation:
Convert the height of the sandbox to feet:
Height in feet
=
18
inches
12
=
1.5
feet
Height in feet=
12
18inches
=1.5feet
Calculate the volume of the sandbox:
Volume
=
Length
×
Width
×
Height
Volume=Length× Width× Height
Since we don't have the dimensions (Length and Width), we can't calculate the exact volume. However, let's use a general formula:
Volume
=
Length
×
Width
×
1.5
feet
Volume=Length×Width×1.5feet
Determine the number of bags needed:
Number of Bags
=
Total Volume
Volume per Bag
Number of Bags=
Volume per Bag
Total Volume
Given that each bag is 3 cubic feet:
Number of Bags
=
Volume
3
Number of Bags=
3
Volume
Without the specific dimensions of the sandbox, we cannot provide an exact number of bags, but you can use these formulas once you have the length and width of the sandbox. For example, if the sandbox is 3 feet by 3 feet, then the volume would be
3
×
3
×
1.5
=
13.5
3×3×1.5=13.5 cubic feet, and the number of bags needed would be
13.5
3
=
4.5

13.5
=4.5 bags. In this case, Sheldon would need to purchase 5 bags to ensure he has enough sand to fill the sandbox.
4 bags" of sand will he need to purchase to fill the sandbox. So, the correct option is "c" " 4 bags".
