Mathematics

maxonik [38]3 years ago

Answer:

9 9/20

Step-by-step explanation:

4 1/5 * 2 1/4

Change the mixed nubers to improper fractions

4 1/5 = (5*4+1)/5 = 21/5

2 1/4 = (4*2+1) /4 = 9/4

21/5 * 9/4 = 189/20

Now we change it back to a mixed number

20 goes into 189   9 times   (20*9 = 180  with 9 left over)

9 9/20

Work out the volume of this prism.
aniked [119]

Answer:

Volume = 175 cm³

Step-by-step explanation:

We can picture this image as a whole rectangular prism, with a part that has been cut out of it.

Step 1: Volume of original prism

We are going to solve the volume of the original prism, with the dimensions of 9, 7, and 5

  • V = 9 * 7 * 5
  • V = 315

Step 2: Volume of part cut out

We are solving the volume of that part that has been cut out ( missing space)

  • V = 5 * (9-2) * (7-3)
  • V = 5 * 7 * 4
  • V = 140

Step 3: Total Volume

Now we just subtract the cutout part from the original volume

  • 315 - 140
  • V = 175

Volume = 175 cm³

Note, we could have also found the volume by splitting this shape into two prisms with dimensions (9 * 3 * 5) and (4 * 5 * 2). This way would also get us:

  • V = (9 * 3 * 5) + (4 * 5 * 2)
  • V = 135 + 40
  • V = 175
