Answer:
Third block is the biggest,
Step-by-step explanation:
Since size of a block is a three dimensional property and decided by the volume.
Formula of the volume of a prism of block is,
V = Length × width × height
Volume of block (1) = 1 × 1 × 7 = 7 m³
Volume of block (2) = 5 × 5 × 1 = 25 m³
Volume of block (3) = 3 × 3 × 3 = 27 m³
This reveals, volume of block (3) is maximum and volume of block (1) is the least.
Therefore. [tex]V_3>V_2>V_1[/tex] is the decreasing order of the volumes of the given blocks.
Third block is the biggest of all three.
