Question

Help The area of a square

Answer 1

`\sf 2551\frac12 \ cubic \ inches`

Explanation:

volume of a cuboid = width × length × height

Given:

• 
  `\sf width=10\frac12 \ in`
• 
  `\sf length=20\frac14 \ in`
• 
  `\sf height=12 \ in`

Substituting given values into the formula for volume:

`\sf \implies volume=10\frac12 * 20\frac14 * 12`

`\sf =(21)/(2) * (81)/(4) * (12)/(1)`

`\sf =(21 * 81 * 12)/(2 * 4 * 1)`

`\sf =(20412)/(8)`

`\sf =2551\frac12 \ in^3`

Answer 2

`2551(1)/(2)`

Explanation:

`\bf l = 20(\sf 1)/(4) \ in = (81)/(4) \ in`

`\bf w = 10(1)/(2) = (21)/(2) \ in\\\\\\h = 12 \ in`

Volume of rectangular prism = l*w*h

`= (81)/(4)*(21)/(2)*12\\\\\\= 81 *(21)/(2)*3\\\\\\= (5103)/(2)\\\\\\= 2551 (1)/(2) \ cubic \ inches`
