Question

5 cubes of side 8 cm are melted to form a cuboid of square base with height 10 cm find the side of square base of the cuboid so formed

Answer 1

Area of a parallelogram = Base × Corresponding Height. • Area of ... Lateral surface area of a cuboid = 2 × height × (length + breadth). ..... A cube of side 5 cm is painted on all its ..

Answer 2

since the cuboid has a square base therefore its length and breadth are same.let the length of cuboid=a

the breadth of cuboid=a

the height=10 cm

side of cube= 8 cm

volume of 1 cube= (8x8x8)cm3=512cm3

volume of 5 cubes= volume of cuboid

=>5x512=axax10

=>(5x512)/10= a2

=>256=a2

=>a=16 cm

Ans: The square base of the cuboid is 16cm by 16cm
