How do you find the length of a rectangular prism when given the volume and height?
volume = h * w * l where h is prism height, w is its width and l its length….Right rectangular prism calc – find V
- Find the box length. For example, it can be equal to 18 in.
- Determine its width. You measured 12 in.
- Find out the rectangular prism height. Assume it’s 15 in.
- Calculate the cuboid volume.
How do you find the height if you have the volume length and width?
Divide the volume by the product of the length and width to calculate the height of a rectangular object. For this example, the rectangular object has a length of 20, a width of 10 and a volume of 6,000. The product of 20 and 10 is 200, and 6,000 divided by 200 results in 30. The height of the object is 30.
What is the formula for finding surface area of a rectangular prism?
The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
How do you find possible dimensions?
Measure all three aspects–the length, width and height–of an object to get a three-dimensional measurement. Continuing the example above, the 3 foot x 4 foot rectangle is the side of a box that has a length of 5 feet, so the dimensions are expressed as 3 ft. (width) x 4 ft.
What is the height of rectangular prism?
Re-work the equation to solve for h: h = 3V / b. So the height is three times the volume, divided by the base’s area.
How do you find the volume and surface area of a rectangular prism?
Once you understand that a rectangular prism includes some sets of identical shapes, it’s much easier to find its surface area and volume. The surface area of a rectangular prism is the sum of the areas of each side, and the volume of a rectangular prism is its length times width times height.
How do you find the surface area and volume?
Surface Area Formulas:
- Volume = (1/3)πr2h.
- Lateral Surface Area = πrs = πr√(r2 + h2)
- Base Surface Area = πr2
- Total Surface Area. = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
