Find the surface area of a cube with e=4.5 cm.
Please help ASAP!!! :(
the surface of a cube is six equal squares
s.a. = 6 * e^2
Why did the cube go to school early?
Because it wanted to be a "square" in its class!
Now, to calculate the surface area of a cube, you need to use the formula:
Surface area = 6 * (edge length)^2
Given that the edge length (e) is 4.5 cm,
Surface area = 6 * (4.5 cm)^2
Solving this, we get:
Surface area = 6 * (20.25 cm^2)
Surface area = 121.5 cm^2
So, the surface area of the cube with an edge length of 4.5 cm is 121.5 square cm.
To find the surface area of a cube, we need to calculate the area of each face. Since all faces of a cube are congruent squares, the area of a face is given by the formula:
Area of a square = side length * side length
Given that the edge length (e) of the cube is 4.5 cm, we can find the surface area as follows:
1. Calculate the area of one face:
Area of one face = e * e = 4.5 cm * 4.5 cm = 20.25 cm²
2. Since a cube has six faces, we multiply the area of one face by 6:
Surface area of the cube = 6 * 20.25 cm² = 121.5 cm²
Therefore, the surface area of the cube with an edge length of 4.5 cm is 121.5 cm².
To find the surface area of a cube, you need to know the length of its edges (e). In this case, the given value of e is 4.5 cm.
The surface area of a cube is calculated by multiplying the length of one side (edge) by itself and then multiplying by 6 (since a cube has 6 equal sides).
So, to find the surface area of a cube with e = 4.5 cm, you can follow these steps:
Step 1: Calculate the area of one face:
The area of one face of a cube is found by squaring the length of one edge.
Area of one face = e^2 = 4.5 cm * 4.5 cm = 20.25 cm^2.
Step 2: Multiply the area of one face by 6:
Since a cube has 6 faces, you need to multiply the area of one face by 6.
Surface area of the cube = (Area of one face) * 6 = 20.25 cm^2 * 6 = 121.5 cm^2.
Therefore, the surface area of the cube with e = 4.5 cm is 121.5 cm^2.
