Real Volume of Cubes & Cuboids practice questions
Four packing boxes have these dimensions. Which one has the greatest volume?
A cube of side 5 cm ✓
A cuboid 4 cm × 5 cm × 6 cm
A cuboid 3 cm × 8 cm × 5 cm
A cube of side 4 cm
The cube of side 5 cm has volume 5 × 5 × 5 = 125 cm³, which is greater than 120 cm³ (4×5×6), 120 cm³ (3×8×5), and 64 cm³ (4×4×4) for the others.
A cube-shaped storage box has a volume of 1,331 cm cubed. What is the length of each side, in cm?
11 cm ✓
12 cm
10 cm
121 cm
11 x 11 x 11 = 1,331, so each side of the cube is 11 cm.
Xin Yi says: 'To find the volume of a cuboid, I just add the length, width and height together.' What is wrong with her statement?
Volume is found by MULTIPLYING length x width x height, not adding them ✓
She is completely correct
Volume should be divided, not added
Cuboids do not have a defined volume
The volume of a cuboid is length x width x height (multiplication), not the sum of the three measurements.
