Answer:

75%

Step-by-step explanation:

First let's start by finding the total number of students at the assembly:

63+21=84

Then we find the percentage of the students that were first-graders.

63/84=9/12=3/4=75/100=75%

As further explanation to how this works:

We take the number of first graders over the total number of students so we can find the percentage. Then we simplify it down to 3/4. Since percentages are out of 100 we can change the fraction so it's something out of 100. We multiply the numerator and denominator by 25 (since 100/4=25) and we get 75/100 which is 75%

Surface area of a 4m and 4m and 4m cube
jeka94

Answer: 96 m²

Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a 3-dimensional figure.

So to find the surface area of a cube, it's important to understand that each face of a cube has the same area so we can simply find the area of one face of a cube and multiply by the number of faces which is 6.

To find the area of one face of a cube, we can use the formula for the area of a square which is S².

Since the length of a side is 4 meters, we have (4 m)² or 4 meters x 4 meters which is 16 m².

Now, since there are six sides to a cube, we have 6 (16 m)² which is equal to 96 m². So the surface area of the cube is 96 m².
