Answer: 67.97%
Step-by-step explanation: BEWARE: THE ANSWER IS NOT 39.56%.
The answer is B) 20
Because you have 5 brands and you combine each with the 4 others, so 5*4=20
The answer is A (or the first one) because the numbers are just switched around but they stay the same.
Alright, lets get started.
The side of square base is given 0.25 in. (say a)
The height of pyramid is given 1.2 in. (say h)
The formula for surface area A is given below:
A=a^2+2a √(a^2/4+ h^2 )
Putting the value of a and h .

Putting the value of a and h

Hence the area of pyramid is 0.6625 square inches. : Hope it will help :)
