Answer:
500
Step-by-step explanation:
10% of people were supporting home and it was 50 people. Multiply 50 by 10 and you get 500. So the total number of people attending the game is 500.
Answer-500
The first step is to find the relationship between the square base and the surface area.
Surface area (SA) = area of the square (SS) + area of triangles.4(AT)
Thus we can conclude area of triangles 4(AT) = SA - SS = 864 - (18*18)
4(AT) = 864 - 324 = 540
Each triangle = 540/4 = 135 square in.
An area of one triangle (AT)= (base* slant height)/2
The base = 18 in.
<span>slant height = 2(AT)/base = 2(135)/18 = 15</span>
Answer:

The volume is 128cm^3
Step-by-step explanation:
Given


Required
Determine an expression for its volume
Find the volume
Volume of a cube is:

Where x represents the length of a side
So, volume of 2 cubes would be:


Solving (b): Volume when x = 4
Substitute 3 for x in 



<em>Hence, the volume is 128cm^3</em>
