Answer:
315 yd cubed
Step-by-step explanation:
To find the volume of the pyramid, we first need to consult the equation below. Thebase is for the rectangular portion, then after multiplied by the height it is divided by 3 to get the pyramid.
To get the base, we multiply the length by the width.
21 * 9 = 189
189 * 5 = 945
945 divided by 3 = 315
Answer:
I =
Step-by-step explanation:
Given
E = 9RI ( isolate I by dividing both sides by 9R )
= I
Answer:
B)
Step-by-step explanation:
That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.
The first step is to find the area of both bases like this:
The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:
Finally, we sum both of the areas found to calculate the total area.
So, the answer is option B).
