What is the formula for the surface area of a trapezoidal prism?
What is the formula for the surface area of a trapezoidal prism?
Answer: The surface area of a trapezoidal prism is h (b + d) + l (a + b + c + d)
What is trapezoidal prism?
A trapezoidal prism is a three dimensional solid that has two congruent trapezoids for its top and lower base. It will have four rectangles that connect the corresponding sides of the two bases. These four rectangles are called the lateral faces of the prism.
How do you find the surface area and volume of a trapezoidal prism?
The surface area of a trapezoidal prism can be given with this formula: (b1+b2)h + PH. In this formula, “b1” and “b2” stand for the length of the bases of the trapezoid. The height of the trapezoid is “h”. The perimeter of the trapezoid is “P”, and “H” is the height of the prism.
Can you explain 2 methods for finding volume of a prism?
A rectangular prism has three dimensions: length (l), width (w), and height (h). Another way to think about the volume formula is as follows: V = l w h = (l w) h. Since l w is the area of the prism’s base, you can think of the volume formula as the area of the base times the height, or V = Bh.
How do you calculate the volume of a trapezoid?
A trapezoid is a two dimensional figure. So you can find the AREA of a trapezoid with the formula A=(1/2)h x (b1+b2) where h is the height and b1 and b2 are the lengths of the parallel sides. Two dimensional figures do not have volume.
What is the formula for calculating the volume of a rectangular prism?
Calculating the Volume of a Rectangular Prism Write down the formula for finding the volume of a rectangular prism. The formula is simply V = length * width * height. Find the length. The length is the longest side of the flat surface of the rectangle on the top or bottom of the rectangular prism. Find the width.
What is the equation for the volume of a pentagonal prism?
The formula for the volume of a pentagonal prism is: Volume = (5/2 × abh) cubic units. Example: If the apothem length ‘a’ of a pentagonal prism is 5 feet, the base length ‘b’ is 4 feet, and the height ‘h’ is 6 feet. The surface area of the pentagonal prism is: 5ab + 5bh = (5 × 5 × 4) + (5 × 4 × 6) = 100 + 120 = 220 square feet. The volume of the pentagonal prism is: 5/2 × abh = 5/2 × 5 × 4 × 6 = 300 cubic feet.
