Question

meena has a cardboard box of 7cm*7cm*2cm .How many such boxes will she require to form a cube​

Answer 1

Answer:

$\boxed{\underline{\Huge{\texttt{28 cuboids}}}}$

Step-by-step explanation:

Length of each edge of cube = L.C.M. of 7 cm,  7 cm and 2 cm, i.e., 14 cm.

Numbers of cuboids = $\frac{\text{(Volume of the cube)}}{\text{(Volume of the cuboid)}}$

                           $= \frac{(14 cm \times 14 cm \times 14 cm)}{(7 cm \times 7 cm \times 2 cm)}$

                           $= \frac{2744}{98} = 28$

                            = 28 cuboids. Answer.
