Measure the height from the bottom to the third-to-last rung of the ladder. For safety reasons, you should never stand on the top two rungs of a step ladder. Since rungs are usually spaced a foot apart, this will take away at least two feet from the usable height of the ladder.

The ladders are either 8' tall (regular) or 12' tall (giant). Yes, this sounds about right. JR always exaggerates things. If you think about it, the giant ones are like twice the height of the wresters (who are like 6ft) so 12' sounds right.

We can use the Pythagorean theorem, a^2 + b^2 = c^2, to calculate the slant height. For both cones and pyramids, a will be the length of the altitude and c will be the slant height. For a cone, b is the radius of the circle that forms the base.

Full-size attic ladders usually need an opening in the ceiling that is at least 22 1/2 x 54 inches. ... If space is tight, look for compact ladder models designed for closets and other small spaces. Some models need only an 18 x 24-inch opening and require less floor space than standard ladders.

Finding the Height of a Triangular Prism Using Surface Area. equals the height of the prism. In order for this method to work you must know the surface area of the prism, as well as the area of the triangular base, and the length of all three sides of the base.

Place one end of the ruler flat on the floor and position it so it's pressed vertically against the wall. Mark the top end of the ruler with a pencil. Then, move the ruler up so the bottom aligns with that pencil mark and mark the new top edge. Repeat this process until you've reached the mark for your height.

Rungs, cleats, and steps of portable ladders (except as provided below) and fixed ladders (including individual-rung/step ladders) shall be spaced not less than 10 inches (25 cm) apart, nor more than 14 inches (36 cm) apart, as measured between center lines of the rungs, cleats, and steps.

The volume of the prism is the area of the base times the height. So to calculate height, divide the volume of a prism by its base area.

The slope of your roof is the ratio of vertical distance (rise) to horizontal distance (run). Just write down the measurements you found. There's no need to simplify them. For example, if you find 4 inches of height with the tape measure at the 12 inch mark on the level, your slope is 4:12 or "4 in 12."

For instance, to measure stairs, break the individual stairs into rectangles and calculate the volume of each individual rectangle. The volume is determined by multiplying the length x width x depth. Once finished, add up the rectangle volumes to find the total volume.

In the ambiguous case we first find the height by using the formula h=bsinA . Note that A is the given angle and its side is always a so the other side will be b . h<a<b then then there are two solutions or two triangles. h<b<a then there is one solution or one triangle.
