Answer 1

Answer:

here is what you need

Step-by-step explanation:

Volume of one cube = 1 x 1 x 1

                                  = 1 cm^3

Hence volume of cuboid will be = 42 x 1 cm^3

                                                     = 42 cm^3

For the cuboid,

perimeter of the base = 18

                       2 (l + b)  = 18                  .............. ( 1 )\

                            l + b   = 9

consider l = 7 and b = 2

Therefore, the volume of cuboid = l x b x h

                                                42  = 14 x h

                                                $\frac{42}{14}$   = h

                                                h    = 3 cm.
