You can observe in the picture attached that the box is a rectangular prism.
The volume of a rectangular prism can be found with this formula:

Where "l" is the length, "w" is the width and "h" is the height.
You know that the lenght of each side of those cubes is 1 centimeter. Therefore, you can multiply the number of cubes on each side of the box by 1 centimeter in order to find the lenght, the width and the height of the box:
Now you can substitute the lenght, the width and the height of the box into the formula shown at the beginning of the explanation:

Finally, evaluating, you get that the volume of the box is:

Answer:

Step-by-step explanation:
→ First step is to find the amount of hours it takes for 5 builders

→ Now we know how long 5 builder takes we need to multiply the hourly rate by their time worked

The ratio is 5:7 when you are dealing with total membership. In other words, out of every 7 members, 5 will be men and 2 will be women
The ratio will look like this
5:7 = x:735 change to a proportion
5/7 = x / 735 Cross Multiply
7*x = 5 * 735 Combine the right
7*x = 3675 Divide by 7
x = 3675/7 Divide
x = 525
Answer: 525 men
