only solids have "lateral area". triangles have "area". the area of a scalene triangle is given by heron's formula. height not needed.
You need to know the area of that cross-section. Once you have that number, the volume of the box is the product of (cross-section area) x (height).
A = 1/2bh then you use Pythagoras theorem to find the length of the other 2 sides, using the known value for the height and 1/2 of the bases value.
Volume = (height)(area base)
If you are only given the side lengths of a scalene triangle, it is impossible for you to find for the area, unless you are given more information... like the height of the triangle for example. If this is a right triangle you would like to find the area of, you can multiply the length of each leg with each other, and then divide that product by 2 to conclude the area of the triangle.
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.
You cannot.
To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.
You cannot.
The radius of a cylinder given only the height could be anything you like.
You don't. You need the height and the area of the base to find the volume.
It matters on what figure it is.
So, you divide the base by 2. Then, you divide the area by that answer and you'll find the height.
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
By dividing length times width into its given volume
Given the information provided in the question, the only answer is to measure it.
