00:00:02.840 --> 00:00:04.800
This is the net of a cube.
00:00:06.000 --> 00:00:11.480
What is the volume of the cube in cubic centimetres?
00:00:11.480 --> 00:00:13.520
We know this is a net of a cube.
00:00:15.200 --> 00:00:17.840
We have to find the volume of this cube.
00:00:18.880 --> 00:00:23.600
But we’re not given the measurements of the lengths of the sides.
00:00:23.800 --> 00:00:30.440
But we are told that the total lengths of four of the squares is 20 centimetres.
00:00:31.760 --> 00:00:36.840
So if we divide 20 by four, this will tell us the length of one side.
00:00:38.200 --> 00:00:40.120
20 divided by four is five.
00:00:41.480 --> 00:00:44.320
So now we have the measurements to mark on our cube.
00:00:45.880 --> 00:00:53.200
To calculate the volume of a cube, we use the formula length times width times height.
00:00:54.640 --> 00:00:58.720
So we need to calculate five times five times five.
00:01:00.120 --> 00:01:02.280
Five times five is 25.
00:01:03.320 --> 00:01:07.040
And 25 times five is 125.
00:01:07.960 --> 00:01:09.880
Four 25s make 100.
00:01:10.200 --> 00:01:13.880
And one more makes 125.
00:01:13.880 --> 00:01:17.160
And we’re asked to write our answer in cubic centimetres.
00:01:18.000 --> 00:01:22.480
So the volume of the cube is 125 cubic centimetres.
00:01:24.360 --> 00:01:30.360
First, we calculated the length of one edge by dividing 20 by four.
00:01:31.440 --> 00:01:37.520
Then, we calculated the volume by multiplying the length times the width times the height.
00:01:38.800 --> 00:01:44.760
Five times five times five is 125 cubic centimetres.
