What is the volume of this cuboid?<br>Please help me!!!?!
Snowcat [4.5K]

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)      <em>use distributive property</em>

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

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

V=3x^2+3x+12x+12      <em>combine like terms</em>

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