Marks: +1, -0

Seven equal cubes each of side 5 cm are joined end to end. Find the surface area of the resulting cuboid.

750 $cm^3$
1500 $cm^3$
2250 $cm^3$
700 $cm^3$

Solution:

(a) Since, seven equal cubes are joined and made a cuboid.
So, length of cuboid = 7 x 5 = 35 cm
breadth of cuboid = 5 cm
and height of cuboid = 5 cm
Now, surface area of resulting cuboid = 2 (lb + bh + hl)
= 2 (35 x 5 + 5 x 5 + 5 x35)
= 2(175 + 25 + 175)
= 2 x 375
= 750
