2 square pyramids are connected at their base. The square base is 33 millimeters, and the height of the triangular sides are 28.6 millimeters. This 8-sided octahedron is a composite figure consisting of 2 square pyramids. The base of the pyramid is 33 mm, and the slant height is 28.6 mm. What is the surface area of the octahedron? mm2

susie has 7 apples

answer is 33

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
