1 Let its height be 12x and its width be 5x
2 So: 0.5*12x*5x*40 = 7500 or 1200x2 = 7500 cm3
3 Divide both sides by 1200 and then square root both sides
4 Therefore: x = 2.5 so height is 12*2.5 = 30 cm and width is 5*2.5 = 12.5 cm
5 Hypotenuse: 13*2.5 = 32.5 cm because it's a Pythagorean triple
6 Area: (2*0.5*30*12.5)+(30*40)+(12.5*40)+(32.5*40) = 3375 cm2
7 Check: 0.5*30*12.5*40 - 7500 cubic cm

What is the formula for finding the total surface area of a triangular prism?
Assume that a = apothem length of the triangular prism, b = base length of the triangular prism, and h = height of the triangular prism. The formulas to find the surface area is SA = ab + 3bh.

How does the net of a triangular prism help you find the surface area of the prism?
A triangular prism has 5 sides. Three are rectangles and two are triangles. If you fold the net out flat you can get the dimensions and find the surface area. Each rectangle is length by width. And the triangles should be congruent and remember are length times height divided by two.
How do you find length and width of a square showing only the height of the square?

Height of a triangular based pyramid?
The height of a triangular based pyramid is given by h=2V/(bxl). V is its volume, b its base and l its length.
