The cost need to put a 0. 5 ft layer of topsoil on the entire garden is $1000
According to the given statement
we have given that the
side length of the square garden is 10ft.
topsoil cost per foot is $5
And we have to find the cost which required to put a 0. 5 ft layer of topsoil on the entire garden.
So,
The side length of the square garden is 10ft.
Now, the volume of the cube is (a)^2
And
Total volume of cube = 10*10
Total volume of cube = 100 per square foot.
Now, we find the cost required for a topsoil.
Cost required to put a topsoil of 1 foot in the total volume of cube = volume*cost
So,
Cost required to put a topsoil of 1 foot in the total volume of cube = 1000*5
Cost required to put a topsoil of 1 foot in the total volume of cube = $5000
if we put a topsoil of 0.5 feet then
The cost required = $5000/0.5
The cost required = $1000.
So, The cost need to put a 0. 5 ft layer of topsoil on the entire garden is $1000
