The base of each candle is a square of perimeter 20 cm.
Rosa needs to know the volume of one candle.
Work out the volume of one candle.
Remember to give units with your answer

Answer 1

The volume of one candle is 200 cm³.

Step-by-step explanation:

The base of each candle is a square with a perimeter of 20 cm. Since the perimeter of a square is 4 times the length of one side, we can divide 20 cm by 4 to find the length of one side of the square base. So, each side of the square base is 5 cm.

Now, the height of the candle is given as 8 cm.

To calculate the volume of the candle, we can use the formula for the volume of a cuboid, which is length x width x height. In this case, the length and width of the base are both 5 cm, and the height is 8 cm. So, the volume of one candle is 5 cm x 5 cm x 8 cm = 200 cm³.

Answer 2

To find the volume of the candle, you need to find the volume of the cuboid. The volume of a cuboid is found by multiplying the length, width, and height.

First, you need to find the length and width of the base. The perimeter of the base is 20 cm, and since the base is a square, all four sides are the same length. You can divide the perimeter by 4 to find the length of each side:

20 cm / 4 = 5 cm

So, each side of the square base has a length of 5 cm. This means the length and width of the base are both 5 cm.

Now that you know the length, width, and height of the cuboid, you can calculate the volume:

Volume = length * width * height
= 5 cm * 5 cm * 8 cm
= 200 cm^3

So, the volume of the candle is 200 cm^3.
