Volume and Surface Area! 30 POINTS

Volume: 5200 cubic centimeters

Surface area: 1520 square centimeters

Step-by-step explanation:

Volume = [1/2 x 5 x side x apothem] x height

(The apothem is that little 8 cm mark, the height is 26, the side is 10.)

Plug those values in:

V = 1/2 * 5 * s * a * h

  =  1/2 * 5 * 10 * 8 * 26 = 5200 cubic centimeters

Surface area = 2(base area) + 5(lateral area)

SA = 2(200) + 5(260) = 1520 square centimeters

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
