00:21 And this is the solution to the question

Step-by-Step Solution

To solve this problem, let's determine the missing dimension X X by applying the formula for the volume of a cuboid:

  • Step 1: Identify given values: Volume V=90 V = 90 , Height H=5 H = 5 , Length L=3 L = 3 .
  • Step 2: Use the volume formula: V=L×W×H V = L \times W \times H .
  • Step 3: Substitute the known values: 90=3×X×5 90 = 3 \times X \times 5 .
  • Step 4: Simplify and solve for X X . First, calculate 3×5 3 \times 5 , which is 15 15 .
  • Step 5: Rearrange the equation: 90=15×X 90 = 15 \times X .
  • Step 6: Solve for X X by dividing both sides by 15: X=9015 X = \frac{90}{15} .
  • Step 7: Calculate to find X=6 X = 6 .

Thus, the missing width X X of the cuboid is 6 6 .

Answer

6 6
