Question

Three cube each of side 43 cm are joined end to end. Find the surface area and volume of the solid so formed​

Answer 1

Answer:

Length of each side of cube = 5 cm

Now, 3 cubes are joined end to end.

So, the length of the resulting cuboid will be = 5+5+5 = 15 cm

But, the breadth and height will remain the same.

So, Breadth = 5 cm and Height = 5 cm

Surface area of the cuboid = 2(LB + BH +HL)

= 2(15*5 + 5*5 + 5*15)

= 2(75 + 25 + 75)

= 2*175

Surface area of the cuboid = 350 sq cm
