To get the distance DC we proceed as follows:
AB-CD
=11-3
=8
BC=15
hence using Pythagorean theorem
c²=a²+b²
c=DC
a=BC
b=8
thus
c²=15²+8²
c²=225+64
c²=289
thus
c=√289
c=17 units
Answer: B. 17 units
We can see here that there are 2 triangular bases on the prism.
To calculate the area of a triangle, we multiply the base and the height and then divide by 2.
A = 8 x 6 /2
A = 48/2
A = 24
Hope it helps!
The original equation: 8(5.95)+8(4)+8(3.60)+8(2.25)= $126.4
To answer the question you should add all of the numbers within the parenthesis together: 5.95+4+3.60+2.25= $15.8
Then multiply that answer times the total number of people: 8(15.8)= $126.4
