Question

the dimensions of a cuboid are in the ratio of 3:2:1 and the total surface area is 1078sq cm. find its volume

Answer 1

Step-by-step explanation:

Let the dimension l=3x, b=2x ,h=X

Surface Area = 2(lb+BH+HL)

2(6x^2+2x^2+3x^2)

2(11x^2)

22x^2 = 1078

x^2=49

X=7

l=3x7=21 cm

b=2x7=14 cm

h= 7 cm
