What is the volume of this cuboid? 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:

$V=(x+4)(x+1)(3)$ 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

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

A mango weighs 36 ounces. The total weight of 3 magoes and 1 apple is the same as the weight of 5 apples. How much does 1 apple

Vadim26 [7]

Data:

M (mango)
A (apple)

We have:
1M = 36 ounces
3M + 1A = 5A

Replace and solving:

$3M + 1A = 5A$
$
3.(36) + 1A = 5A$
$108 + 1A = 5A$
$108 = 5A - 1A$
$108 = 4A$
$4A = 108$
$A = \frac{108}{4}$
$\boxed{A = 27}$

Answer:
Aple weigh 27 ounces
