Answer:
I really need the points
Step-by-step explanation:
So I do not know.
Anyhow... look at the picture below
so... a triangular prism, is just 2 triangles and 3 rectangles stacked up to each other at the edges, that's all they mean by the "net" bit
so.. get the area of each triangle, and each rectangle, and sum them up, that's the area of the triangular prism
you pretty much have all values, notice, the triangles have a height of 3 and a base of 4
Answer:
Width = 16(√5) - 1
Step-by-step explanation:
We are told that the golden rectangle is 32 cm long.
Thus, length = 32 cm
We are also told that the ratio of the length to the width is; (1 + √5):2
Thus;
If a length of (1 + √5) yields a width of 2
Then, a length of 32 cm would yield a width of; (32 x 2)/(1 + √5)
So corresponding width = 64/(1 + √5)
We want to reduce this width to it's simplest radical form which means the denominator should have no square root.
Thus, let's multiply top and bottom by (1 - √5);
Width = 64 x (1 - √5)/[(1 + √5) x (1 - √5)]
Width = 64(1 - √5)/(1 - 5)
Width = 64(1 - √5)/(-4)
Width = -16(1 - √5)
Width = 16(√5 - 1)
Width = 16√5 - 1
