The Easy Way to Calculate Surface Field Four Regular

The Easy Way to Calculate Surface Field Four Regular - what is referred to as a field of four regular? four irregular field is waking up space consisting of four field side of the shape of an equilateral triangle. Four irregular field more commonly known as a triangular pyramid-shaped irregularly because the whole side of the equilateral triangle. So how do I calculate the surface area of ​​this triangular pyramid? refer to the discussion of Mathematical Formulas Basic below:

How Fast Searching Surface field Four Regular

First you must consider the equilateral triangle pyramid image (field four irregular) T.ABC following:

When noted, in the wake of the room above there four equilateral triangles of course the same extent. the equilateral triangle that is ΔABC, ΔBCT, ΔACT, and ΔABT. the formula is easy and fast to compute lkuas equilateral triangle are:

L.Δ = ¼s2√3

There are four surfaces in four (equilateral triangle pyramid) of the same size in the picture above, then:

L = 4 × L.Δ

L = 4 × ¼s ^{2 [1945922million] √3}

L = s ^{2 [1945922million] √3}

Thus, the formula to find the volume (V ) field has a length of four irregular rib (s) are:

L = s ^{2 [1945922million] √3}

Example Problem 1:

Given a uniform field of four ribs 8 cm in length. What surface area of ​​four squiggly?

Solved:

L = s ² √3

V = (8 cm) ² √3

V = 64√3 cm ²

Thus, the irregular surface area of ​​four is 64√3 cm ^{2 [1945922million]}

that Easy way to Calculate Surface field Four Regular (equilateral triangle pyramid) when the length of the ribs telkah known. Hopefully, you can understand the above very well.
