Answer: 221.4 m³ If you are just looking for the volume of the triangular prism.
Step-by-step explanation: Volume of the prism is the Area of the base times the height.
The Area of the triangular base = width × height ÷ 2
Width = 12m height = 4.1m = 49.2m Divided by 2 =
24.6m² is the Area of the base
The height of the base is 9m
24.6 × 9 = 221.4 cubic meters
Step-by-step explanation:
Let "c" be the original number of classrooms.
The 1200/c was the original number of students per classroom.
----
Equation:
1200/(c-4) = (1200/c)+10
Multiply thru by c(c-4)
---
1200c = 1200(c-4)+10c(c-4)
---
1200c = 1200c-4800 + 10c^2-40c
----
10c^2-40c-4800 = 0
c^2-4c-480 = 0
Factor:
(c-24)(c+20) = 0
---
Positive solution:
c = 24 (# of classrooms originaly planned)
