Find the surface area of the prism.

s = 2b + PH  

s =  4(3 * 4) + (8)(96) =

s = 4(12) + (8)(96)

s =  48 + (8)(96)

s = 48 + 768

s =  816

the radius is 2 times the diameter.

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
