Jim is going to refinish the top and sides of an old wooden storage chest shaped like the cube shown below
(there is a picture of a cube with the measurement 19.5 inches)
Which is the closest to the surface area in square inches that Jim is going to refinish?
Please help I'm stuck on this problem
19.5^2 * 6 = _______ square inches
Thanks.
You're welcome.
Is ^ square root? Second power? Multiply? What does it mean?
Second Power.
To find the surface area of a cube, you need to calculate the area of each face and then sum them up.
In this case, since the cube has all equal sides, you just need to calculate the area of one face and then multiply it by 6 to account for all the faces.
The formula to calculate the surface area of a cube is S = 6s², where S represents the surface area and s represents the length of one side.
In this problem, the length of one side is given as 19.5 inches. Plugging this value into the formula:
S = 6 * (19.5 inches)²
To square 19.5 inches, you multiply it by itself:
S = 6 * (19.5 inches * 19.5 inches)
Now you can calculate the surface area:
S = 6 * (380.25 inches²)
Simplifying the equation:
S = 2281.5 inches²
Therefore, the closest measurement to the surface area that Jim is going to refinish is approximately 2281.5 square inches.
