I'm giving out Brainliest!

Answers

Step-by-step explanation:

step 1. V = LWH. L = length. W = width. H = height.

step 2. V = (912)(312)(612) = 174,140,928 in^3.

The volume of Maria's new fish tank is 174,140,928 cubic inch.

It is required to find  the volume of Maria's new fish tank.

What is cuboid?

In geometry, a cuboid is a solid shape or a three-dimensional shape. A convex polyhedron that is bounded by six rectangular faces with eight vertices and twelve edges is called a cuboid.

Given :

Maria has a new fish tank for her goldfish.

The fish tank is in the shape of cuboid.

length=912 inches

width=312 inches

Height=612 inches

Part A

The formula of volume of her new fish tank

Volume=length ×width × height.

Part B

Volume=length ×width × height.

By the use of formula we have,

V = (912) ×(312) ×(612)

V= 174,140,928 cubic inch.

Therefore, the volume of Maria's new fish tank is 174,140,928 cubic inch.

years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.
