The formula of a volume of a cuboid:


V=lwh

l - length

w - width

h - height

We have:

l = (x + 4) cm

w = (x + 1) cm

h = 3 cm

Substitute:


V=(x+4)(x+1)(3) use distributive property


V=(x+4)(3x+3)


V=(x)(3x)+(x)(3)+(4)(3x)+(4)(3)


V=3x^2+3x+12x+12 combine like terms


\boxed{V=3x^2+15x+12}
