Question

a rectangular solid 4.3 cm high has a square base of side 6.7 cm.Find its volume

Answer 1

volume= (6.7 × 6.7 × 4.3 ) cm
=193.027 cm3

Answer 2

volume of a cuboid = lxbxh(length x breadth x height)
so,  as the base is a square lxb = area of the square 
                                                   = side x side
                                                   = 6.7 x 6.7
                                                   =44.89
volume of the solid = base x height
                               = 44.89 x 4.3
                               = 193.027
 hope this helps
