Cuboid has 6 faces. If each face was 2m squared, that would be 2m squared times 6 which is 12m squared
105 divided by 6 equals 17. 5

Area of a triangle=bh/2
27= x(x-3)/2
27= (x^2-3x)/2
54= x^2-3x
x^2-3x-54=0
(x-9)(x+6)=0
x=9, x=-6.
In this case, x must equal 9 since the base cannot be a negative number.
Final answer: Height=6 m
