Paulita is going to build a storage cube. Each edge is 14 inches .the wood cost $ 0.03 per square inch .use 0.03(5e2) where e is the edge length to evaluate for e =14
To find the cost of the wood, we need to calculate the surface area of the cube.
The surface area of a cube can be calculated by multiplying the length of one side by itself and then multiplying by 6 (since a cube has 6 sides of equal length).
So, the surface area of the cube with edge length 14 inches is:
Surface Area = (14 inches) x (14 inches) x 6
Surface Area = 1176 square inches
Now, let's calculate the cost of the wood:
Cost = (0.03) x (1176)
Cost = 35.28 dollars
Therefore, the cost of the wood for the storage cube with an edge length of 14 inches is $35.28.
To evaluate the cost of the wood for the storage cube, we need to find the surface area of the cube first. Since all the edges are 14 inches each, we can use the formula for the surface area of a cube, which is given by:
Surface Area = 6 * (edge length)^2
So, for the given edge length of 14 inches:
Surface Area = 6 * (14)^2
= 6 * 196
= 1176 square inches
Now, we can calculate the cost of the wood by multiplying the surface area by the cost per square inch. The cost per square inch is given as $0.03. Therefore:
Cost of Wood = Surface Area * Cost per square inch
= 1176 * 0.03
= $35.28
Hence, the wood cost for building the storage cube is $35.28.
To calculate the cost of the wood for building a storage cube with edges measuring 14 inches, we need to find the surface area of the cube and multiply it by the cost per square inch.
The surface area of a cube can be found by multiplying the length of one edge by itself and then multiplying the result by 6 (since a cube has 6 faces). In this case, the edge length is 14 inches, so the surface area (A) is:
A = 14 * 14 * 6 = 1176 square inches
Now, we can calculate the cost of the wood by multiplying the surface area by the cost per square inch. Given that the cost per square inch is $0.03, we have:
Cost = A * $0.03 = 1176 * $0.03
To evaluate this expression, we can use the given expression 0.03(5e2), where e is the edge length (14). Let's substitute e with 14:
Cost = 0.03(5 * 14^2)
Simplifying further:
Cost = 0.03(5 * 196)
= 0.03 * 980
= $29.40
Therefore, the cost of the wood for building the storage cube is $29.40.
