A pipe that's 36 inches long needs to be cut into 2 and one forth inches long pieces. how may pieces can be cut from this length
PolarNik [594]
16 pieces may be cut. This is because we need to divide 36 by 2 and 1/4 to find how many pieces hat can be cut. First, we need to change everything into a fraction (or improper fraction). 2 and 1/4 = 9/4 (if you need help trying to find out how to get this, just ask). Then, since we are doing division, we flip the 9/4 around to get 4/9. 36 times (it's not dividing anymore since we flipped the 9/4) 4/9 = 16 pieces. I hope this helps! :D

Answer:

Step-by-step explanation:

We are given the an area of

173.6 cm

and a height of 9 cm.

We also know that the formula for area is lw, meaning we can substitute the area for lw

in the volume formula.

Now let's plug in what we know into the formula and solve for the volume:

V=(173.6 cm2)(9 c)=1562.4 cm3 The volume of the rectangular prism is

1562.4 cm3
