This is a homework question, WikiAnswers does not do homework for people, because that is cheating.
To help you, the prism will have a triangular base where the triangle is an equilateral triangle (all edges are the same length)
The interior angles of an equilateral triangle are all 60 degrees.
The square root of 12cm is 3.46 cm
the length of the prism is 4 cm
To work out the answer
(1) work out the area of the triangle - you will need to bisect one angle to make 2 identical right angle triangles inside the bigger equilateral triangle. This bisecting line will be 3.46 cm and the triangles will have internal angles of 90, 60 and 30 degrees. Using this information and Pythagoras' theorem you will be able to work out the length of a side of the equilateral triangle.
Once you have this length, the area of an equilateral triangle is provided by the formula.
Area = sqrt(3)/4 a2 (where "a" is the length of a side)
(2) multiply this by the length.
Further Information:
Using trigonometry each side of the triangle: square root of 12/sin(60 degrees)=4 cm
Volume: 0.5*4*4*sin(60 degrees)*4=27.713 cubic cm rounded up to 3 decimal places
The answer depends on what sort of triangle: right angled, equilateral, isosceles or scalene.
The base length is 5.2643 units and the height is 4.55902 units.
the height is the same as the length and width
The height of a triangular based pyramid is given by h=2V/(bxl). V is its volume, b its base and l its length.
square root (3) * side length / 2
The answer depends on what sort of triangle: right angled, equilateral, isosceles or scalene.
base*height*length*.5
One half base times height (of the triangular section) times length.
Cutting the equilateral triangle in half results in two right triangles each with a base of length x/2, and angles of 30, 60, and 90 degrees. Using the lengths of sides of a 30-60-90 triangle it can be found that the height is (x/2)√(3), which is the same as the height of the equilateral triangle.So the height of the equilateral triangle is x√(3) / 2.
That's an "equilateral triangle". Each inside angle is 60 degrees.
The base length is 5.2643 units and the height is 4.55902 units.

square root (3) * side length / 2
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.
Length of triangular prism: 1037.4/(0.5*13*13.3) = 12 yards
Think in 3-dimensions and make a tetrahedron (a triangular pyramid).
