Question

the dimensions of a cuboid are in the ratio of 2:3:4 it's TSA is 468 square m find the dimensions​

Answer 1

Answer:

dimension are 6,9,12 cm

Step-by-step explanation:

let the sides be 2x ,3x, 4x

T.S.A of cuboid = 2( lb + bh + hl )

= 2( 6x^2 + 12x^2 + 8x^2)

2(26x^2)

=52x^2

A/Q

52X^2 = 468 m^2

X^2 = 9 m^2

x = +- 3

side cant be -ve therefore x = 3

hence side will be 2(3) = 6 , 3(3) = 9 and 4(3) =12

dimension are 6,9,12 cm
