Answer: ![90cm^3](https://tex.z-dn.net/?f=90cm%5E3)
Step-by-step explanation:
A rectangular prism is a three-dimensional solid.
A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.
You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters (
).
Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:
![V_{prism}=5*V_1](https://tex.z-dn.net/?f=V_%7Bprism%7D%3D5%2AV_1)
Where
is the volume of one layer.
Substituting, you get:
![V_{prism}=(5)(18cm^3)\\\\V_{prism}=90cm^3](https://tex.z-dn.net/?f=V_%7Bprism%7D%3D%285%29%2818cm%5E3%29%5C%5C%5C%5CV_%7Bprism%7D%3D90cm%5E3)
heyy thanks bro you too take care and stay safe!!!
3(10+2)=3(12)=36 or
5(6+2)=5•6+5•2
=30+10
=40
We can use ratios here. The real size would have to be proportional, meaning that if I increase the line on the drawing 5 times, the real size would have to increase 5 times as well.
We can obviously see, after having said that, that the real window would have to be 35ft long (because we multiplied 1 inch by 5, and if 1 inch represents 7 feet, then we also have to multiply that by 5 so it’s proportional, and 7*5=35)
We can check too — 1 in : 7 ft = 5 in : x ft
x = (7ft * 5in) / 1in — we would get the same result :)
