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.
