Question 1: Calculate the volume of a cuboid with length 8 cm, width 5 cm, and height 3 cm.

Answer: 120

Question 2: Find the surface area of a cuboid with dimensions 10 cm by 4 cm by 6 cm.

Answer: 208

Question 3: A cuboid has a volume of 150 cm³. If its length is 10 cm and width is 5 cm, what is its height?

Answer: 3

Question 4: Construct a cuboid on the grid with dimensions: length 6 cm, width 3 cm, and height 4 cm. Show all measurements.

Answer:

Question 5: Plot the graph of y = 2x from x=0 to x=10. Use the grid for accurate plotting.

Answer:

Question 6: A box is in the shape of a cuboid with a length of 12 cm, width of 9 cm, and height of 5 cm. How many such boxes can fit into a larger cuboid measuring 48 cm by 36 cm by 15 cm?

Answer: 8

Question 7: If you increase the length and width of a cuboid by 2 cm each, but keep the height the same, how does the surface area change?

Answer: Surface area increases by 32 cm²

Question 8: Identify the common mistake: A student calculates the surface area of a cuboid as 2(lw + lh + wh) but forgets to double the sum. What is the error and how should it be corrected?

Answer: The error is missing the multiplication by 2; correct formula is 2(lw + lh + wh).

Question 9: Given a cuboid with surface area 94 cm² and height 4 cm, find possible length and width combinations assuming length = width.

Answer: l = w = 3.5 cm

Question 10: Challenge: A cuboid's volume is doubled by increasing only its length. If original dimensions are 5 cm by 3 cm by 4 cm, what is the new length after doubling the volume?

Answer: 10 cm
