GIVEN -
cube of edge = 7 cm.
TO FIND -
TOTAL SURFACE AREA OF RESULTING CUBOID
SOLUTION -
Length of the resulting cuboid = 14 cm (l)
(l)Breadth of the resulting cuboid = 7 cm (b)
(b)And the height of the resulting cuboid = 7 cm (h)
(h)The total surface area of the cuboid is = 2 (lb+bh+lh)
= 2 ( 14 × 7 + 7 × 7 + 14 ×7 )
= 2 ( 98 + 49 + 98)
= 2 ( 245)
= 490 cm²
HENCE THE TOTAL SURFACE AREA OF RESULTING CUBOID IS 490 cm²
