														`"Here, we have " l = 3, b=4, h=5" (Given)"`
  `"Diagonal"^2 = l^2 + b^2 + h^2`
  `"Diagonal"^2 = 3^2 + 4^2 + 5^2`
  `"Diagonal"^2 = 50`
  `Diagonal = 7.0711`
 
  `"Here, we have " l = 3, b=4, h=5" (Given)"`
  `"Volume" = l * b * h`
  ` = 3 * 4 * 5`
  ` = 60`
 
  `"Here, we have " l = 3, b=4, h=5" (Given)"`
  `"Total Surface Area" = 2 (lb + bh + lh)`
  ` = 2 * (3 * 4 + 4 * 5 + 3 * 5)`
  ` = 2 * (47)`
  ` = 94`
 
  `"Here, we have " l = 3, b=4, h=5" (Given)"`
  `"Curved Surface Area" = 2h (l + b)`
  ` = 2 * 5 (3 + 4)`
  ` = 70`
