How many degrees inside a pentagon
WebFeb 11, 2024 · Using this, we can start with the maths: A₀ = a × h / 2. = a × √3/2 × a / 2. = √3/4 × a². Where A₀ means the area of each of the equilateral triangles in which we have divided the hexagon. After multiplying this area by six (because we have 6 triangles), we get the hexagon area formula: A = 6 × A₀ = 6 × √3/4 × a². WebWe know, dodecahedron's volume (V) = 7.66 × a 3 cubic units. Given, a = 0.43 in. Substituting the value of a in the volume formula, we get, V = 7.66 × (0.43) 3 cubic inches. Therefore, the volume of the dice is 0.609023 in 3. Example 3: The sum of the length of all the edges of a regular dodecahedron is 150 in.
