Question

4 cube of volume 125 cm cube each are joined end to end in a row find the surface area and volume of the resulting cuboid

Answer 1

HI THERE!!!!!!!!!!!!!!!!

ANSWER: Volume of cube = 125cm³

                                        a³=125

                                        a=5cm

length of cuboid = 5+5+5+5= 20cm

breadth of cuboid =5cm

height of cuboid = 5cm

Surface area of cuboid = 2(lb+bh+hl)

                                       =2(20*5+5*5+5*20)

                                       =2(225)

SURFACE AREA OF CUBOID = 450cm²

Volume of cuboid = l*b*h

                              =20*5*5

                              =500

VOLUME OF CUBOID = 500CM³
