Answer:
18 bags
Step-by-step explanation:
Both sandboxes have a height of 1 ft. Hence, we consider their areas.
Area of sandbox 1 = [tex]8\times8=64[/tex]
Area of sandbox 2 = [tex]6\times4=24[tex]
64 square foot = 48 bags
24 square foot = [tex]\frac{48}{64} \times24=18[tex] bags
Answer: 18 fifty-pound bags of sand will be needed.
Step-by-step explanation:
The sandbox is in the shape of a cuboid. The formula for determining the volume of a cuboid is expressed as
Volume = L × W × H
The website says that you’ll need 48 fifty-pound bags of sand to fill a sandbox that measure 8ft by 8ft by 1ft. The volume of the sandbox would be
Volume = 8 × 8 × 1 = 64 ft³.
To find the number of many bags that you would need for a sandbox 6ft by 4ft by 1ft, we would find the volume first.
Volume = 6 × 4 × 1 = 24 ft³
Therefore,
If a 48 fifty-pound bags of sand will fill 64ft³ a sandbox,
Then x fifty-pound bags of sand will fill 24ft³ a sandbox.
x = (24 × 48)/64 = 18
