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.
What is the Surface area of a triangler prism?
Triangular Prism: (Breadth x Height) + (3 x Length x Breadth) By Austin from a Christian school in Belrose
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.
What is the surface area of the regular pyramid given 9 and the height is 9?
To calculate the surface area of a regular pyramid, we need the area of the base and the area of the triangular faces. Assuming the base is a square with a side length of 9, the area of the base is (9^2 = 81). The slant height can be calculated using the height of 9 and half the base length (4.5) using the Pythagorean theorem. Finally, the total surface area is the base area plus the area of the four triangular faces.
How do you find length and width of a square showing only the height of the square?
the height is the same as the length and width

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.
The formula for finding the volume of a triangular prism?
A triangular prism can be thought of as a stack of triangles. Then the volume is equal to the area of the triangular base multiplied by the height of the prism, or 1/2 length * width * height.
