Answer 2

Hello there !

question:-

surface area of cuboid is 236cm find length if breadth and height are 5cm and 8cm respectively

Given :-

S.A = 236 cm²

breadth = 5 cm

height = 8 cm

To find :-

Length of the cuboid

Solution :-

$total \: surface \: area \: of \: cuboid \: = 2(lb + bh + hl)$

putting the values in the formula:-

$236 = 2(l(5) + 5 \times 8 + 8(l)) \\ 236 = 2(5l + 40 + 8l) \\ 236 = 2(13l + 40) \\ 236 = 26l + 80 \\ 156 = 26l \\ l = \frac{156}{26} = 6$

therefore, the length of the rectangle is 6 cm.
