1.

The dimensions of a closed cuboidal box are in the ratio 5 : 4: 3. If the total surface area is0.94 m', find the dimensions of the box.

Answer»

length 5xends 4x by 3x

two sides 5x by 4x -->2*5x*4x = 40x^2top and bottom 5x by 3x --> 2*5x*3x = 30x^2two ends 2*4x*3x =24x^2so94 x^2 = .94x^2 = .01x = .1.5 * .4 * .3
