The length, breadth, and height of a cuboid are 15 cm, 10 cm, and 8 cm respectively. Find the total surface area of the cuboid.
  • a)
    860 cm2
  • b)
    850 cm2
  • c)
    700 cm2
  • d)
    830 cm2
Correct answer is option 'C'. Can you explain this answer?

Mayank Roy answered  •  Sep 15, 2024
Understanding a Cuboid
A cuboid is a three-dimensional shape with six rectangular faces. To find the total surface area, we use the formula:
Total Surface Area (TSA) = 2(lw + lh + wh)
Where:
- l = length
- w = breadth
- h = height
Given Dimensions
- Length (l) = 15 cm
- Breadth (w) = 10 cm
- Height (h) = 8 cm
Calculatin
... more
1. Calculate lw (length × breadth):
- lw = 15 cm × 10 cm = 150 cm²
2. Calculate lh (length × height):
- lh = 15 cm × 8 cm = 120 cm²
3. Calculate wh (breadth × height):
- wh = 10 cm × 8 cm = 80 cm²
Combining the Components
Now, substitute these values back into the TSA formula:
- TSA = 2(lw + lh + wh)
- TSA = 2(150 cm² + 120 cm² + 80 cm²)
Summing It Up
- TSA = 2(150 + 120 + 80)
- TSA = 2(350 cm²)
- TSA = 700 cm²
Conclusion
Thus, the total surface area of the cuboid is 700 cm². Therefore, the correct answer is option C.

Find the smallest number which can be expressed as the sum of two cubes of natural numbers Options a) 1729 b) 1001 c) 1728 d) 1332 correct answer is option a) how, explain?

Mayank Roy answered  •  Sep 15, 2024
Understanding the Problem
To find the smallest number that can be expressed as the sum of two cubes of natural numbers, we can represent it mathematically as:
\[ n = a^3 + b^3 \]
where \( a \) and \( b \) are natural numbers.
Calculating Cubes of Natural Numbers
Let's calculate the cubes of the first few natural numbers:
- \( 1^3 = 1 \)
- \( 2^3 = 8
