Question

I need help with finding volume of the shape E.

Answer 1

got picture?

Answer 2

Yes.

Answer 3

in short, the shape is just a bunch of rectangles, stacked up to each other at the corners

so... you'd get the area of each of the rectangles
area of a rectangle = width * height

and them sum up all the found areas :)

Answer 4

I don't know what is the height of the rectangles.

Answer 5

is the height 21?

Answer 6

nope,, that's just one of the heights

Answer 7

and that's just the frontal part of the letter

you'd also have to get the backside areas

Answer 8

Do I multiply 10 and 21?
