Plug in numbers. if originally, it was V=1/2 * 1 * 1 * 2=1

tripling the dimensions would be V=1/2 * 3 * 3 * 6=27 

it would be 27 times larger. this could also be found by 3^3, just as doubling would render 2^3

The volume is 27ed. Three dimensions are tripled. 3x3x3=27.

What is the surface area?????

Elenna [48]

The area of a triangle is found using the formula Area = 1/2 x base x height.

Base = 8

Height = 18.

The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.

There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2

Answer:

Cheese: $4\frac{3}{8}$
Milk: $1\frac{2}{3}$
Pasta: $6\frac{1}{4}$

Step-by-step explanation:

Cheese:

$1\frac{3}{4} = \frac{7}{4}$
Set up a proportion: $\frac{\frac{7}{4} }{4} = \frac{x}{10}$
Cross multiply, then divide: 10 × 7/4 = 17.5, 17.5 ÷ 4 = 4.375
$4.375 = 4\frac{3}{8}$

Milk:

Set up a proportion: $\frac{\frac{2}{3} }{4} = \frac{x}{10}$
Cross multiply, then divide: 10 × 2/3 = $6\frac{2}{3}$ , $6\frac{2}{3}$ ÷ 4 = $1\frac{2}{3}$
