The formula for volume is V = (L)(W)(H).  Length, width, and height are multiplied together.  In this case, height is thickness.  Since we are given the total area, length, and width, we just need to solve for the height/thickness.  Plug in the given values:

225 = (25)(18)(H)
225 = 450*H
H = 225 ÷ 450
H =  0.5

The concrete slab is 0.5 feet thick.

98 x 63 – 32 x 69 =
Dahasolnce [82]

Answer:

3966

Step-by-step explanation:

Use order of operations to solve this problem:

  • Parentheses
  • Exponents
  • Multiply (Left to right)
  • Divide (Left to right)
  • Addition
  • Subraction

In your case, there are no parentheses or exponents, so we can skip right the the multiply and divide step. The first multiplication is 98*63=6174. The next step is to do 32*69=2208. Then you minus 6174-2208=3966.

Hope this helps!
