B*H (base*height) divided by 2
Q. base=4 height=5 What the area of this triangle?
A. 4*5=20 20 divided by 2=10
the reason the formula is B*H divided by 2 is cus a triangle put next to another triangle is a square and a squares formula is B*H so sence a triangle is half a square that just means you have to do the same formula but just cut it in half. find a right angle on the triangle and figure out the height and base of the right angle then multiply then divide by 2.
A=1/2*b*h orA=b*h/2
Example 1:Find the area of an acute triangle with a base of 15 inches and a height of 4 inches.Solution:A=1/2*b*hA =1/2*(15 in) * (4 in)A =1/2* (60 in2)
=30 in2

A cube is a symmetrical 3-dimensional shape contained by six equal squares. The formula for finding its area is: A = 6a^2 , where a is the length of the side of each edge of the cube.
Ask Travis Larson he's crazy smart at stuff like that.

Actually, the answer will depend on what you already know about the triangle (or can deduce).
There is not really a formula for a cuboid. Cuboids are solid figures with 6 faces. There are formulas for area and volume of a cuboid.
pretty sure it is ½ x base x height
the formula for the volume of a cuboid is length x breadth x height
derivation of surface area of cuboid
the formula for the volume of a cuboid is quite simple,it is length multiply by width multiply by height.That's all.
Volume of a cuboid = cross-section area times its length
It is the formula for the volume of a cuboid.
Volume = Length * Width * Height
The total surface area of a cuboid with edges of length a, b and c units is 2*(ab + bc + ca) square units.
Volume of a cuboid.
Let its dimensions be a, b and c:- Surface area of the cuboid: 2*(a*b)+2*(b*c)+2*(a*c) in square units
By Euler's formula the number of faces (F), vertices (V), and edges (E) of any convex polyhedron are related by the formula F + V = E + 2. In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges.
The answer depends on what information you have. One possible answer is height = volume divided by base area.
A cuboid has 6 faces, 12 edges, and 8 vertices. Note that 6+8-12 = 2, which is due to Euler's formula F+V-E=2.
