Answer:
The volume of the steps is:
Step-by-step explanation:
Remember that the volume regularly is:
- Volume = height * width * depth.
There are many forms to solve this exercise, but I'll show you two:
1. Imagine that aren't steps but a big solid, then its volume would be:
- Volume of big solid = 60 cm * 60 cm * 120 cm
- Volume of big solid = 432000 cm3
Now you can subtract the volume of a small solid with measures 30 cm * 30 cm * 120 cm (<em>where is the blank for the step</em>):
- Volume of a small solid = 30 cm * 30 cm * 120 cm
- Volume of a small solid = 108000 cm3
Now you subtract:
- Volume of the building steps = 432000 cm3 - 108000 cm3
- <u>Volume of the building steps = 324000 cm3
</u>
2. The building steps are formed by three solid with volume 30 cm * 30 cm * 120 cm, so:
- Volume of the building steps = 3 (30 cm * 30 cm * 120 cm)
- <u>Volume of the building steps = 324000 cm3</u>
(142 + 215 = 357)- you could use 3 hundreds blocks, 5 tens blocks, and 7 ones.... Thats just one of many ways of doing it
