Step-by-step explanation:
Let the length be 4x, breadth be 2x, and height be 3x
then,
total surface area of cuboid
= 2(lb+bh+hl)
= 2 [(4*2)+(2*3)+(3*4)] x sq.
= 2(8+6+12) X sq.
= 2(26) X sq.
= 52 x sq.
- According to question,
52 x sq. = 8788cm square
x sq = 8788/52 cm square
= 169 cm square
x = √(169 cm^2)
= 13cm
Difference between height and length = 4x - 3x
= x
= 13cm
