An 8-sided die is formed when two square pyramids are attached by their bases. the perimeter of the base shape is 6 centimeters. the distance between the tallest points of the two pyramids is 2 centimeters. what is the surface area of the 8-sided figure?

The surface area of the 8-sided figure is 7.5 cm²

Step-by-step explanation:

The perimeter of the base of each square pyramid is 6 centimeters.

So, each side length of the base  

Two pyramids are attached by their bases and the distance between the tallest points of the two pyramids is 2 centimeters.

So, the height of each pyramid = 1 centimeter.

Now, lateral surface area of each pyramid

So, the total lateral surface area of two pyramids  

Hence, the surface area of the 8-sided figure is 7.5 cm²

the answer is c. 23/3

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
