Question

what is the volume of a triangular prism that has a base area of 30 mm2 and a height of 18 mm?

a rectangle has a length of 6 meters and a perimeter of 20 meters. What is the width of the rectangle?

Answer 1

For first question the formula is
VOLUME=BASE AREA * HEIGHT

Answer 2

For the second one, I'll give you a hint.

Perimeter=2(length)+2(width)

In this case,
20=2(6)+2w

Answer 3

find w.

Answer 4

Triangular prism: 30 * 18 = 540 mm^3

Answer 5

the volume is 270mm3
-volume of a triangular prism=1/2xlengthxwidthxheight
-area of the triangular base=1/2xbxh

the width is 4
-to find perimeter you add all the sides
-if 6 is length, their are two sides that have to be 6
-that=12
-20-12=8
-8/2=4

Answer 6

Perimeter:
20 - 12 = 8

The width is 4
