Solution
Step-by-step explanation:
There are 40 tourists and one tent can hold 8 people so number of tents = 40/8 = 5tents
Space for 1 person on ground = 6×3 = 18ft²
Space for 8 person on ground = 8×18= 144ft²
So the base area of pyramid = 144ft²
As it is a square based pyramid
a² = 144 , a=12ft
A person can breathe 48ft³ air
8 people can breathe 48×8 = 384ft³ air
Volume of tent = 384
1/3 a²h = 384 , h = 8ft
For slant height(l),
h²+(a/2)² = l²
64 + 36 = l² , l = 10ft
Lateral surface area = 2al = 2×10×12 = 240ft²
Total surface area =(2al+a²)=240+144=384ft²
Cost of 1ft² = 500
Cost of 384ft² = 500×384 = Rs192000
Cost of 1 tent = Rs190000
Cost of 5 tents = 192000×5 = Rs960000
The total cost of all tents is Rs. 360000
What is an equation?
An equation is an expression used to show the relationship between two or more numbers and variables.
A tent hold 8 people and each person 6ft×3ft space on the ground. For 40 people:
Number of tents = 40/8 = 5 tents
Area for 5 tents = (8 * 6ft * 3 ft) * 5 tents = 720 ft²
Given a cost of Rs. 500/ft^2, hence:
Total cost = 720 ft² * Rs. 500/ft² = Rs. 360000
The total cost of all tents is Rs. 360000
