Question

I have a right rectangular prism, slanted rectangular prism, right triangular prism and a right cylinder. All are the same height. All three prisms have a base measuring 18 square millimeters. (r.r.p. is 9x2, s.r.p. is 3x6, r.t.p. is b=6 h=6). The cylinder's radius is 4mm. Which figures have the same volume? Why?

Answer 1

A = b*h

find all the figures that have a base with the same area as A

Answer 2

Huh?

Answer 3

which of the figures have a base with the same area as A?

Answer 4

and what is A?? I'm lost.

Answer 5

solid A

Answer 6

Ohhhhhh... then solids A, B and C

Answer 7

right

Answer 8

Ummmm... The volume. not area of the base.

Answer 9

the problem says that all the heights are the same, so if the area of the base is the same, then the volume is also the same

V = b*h

Answer 10

Okay. and then the cylinder???

Answer 11

the cylinder has a different base area, therefore it has a different volume...

Answer 12

Okay. Thank you1 :)
