Respuesta :

the length of the fish tank is  [tex]length=13cm[/tex] . Correct option is A)

Step-by-step explanation:

Here we have , Peter has just purchased a small rectangular fish tank that holds 910 milliliters of water. The tank has a width of 7 cm and a height of 10 cm.  We need to find What is the length of the fish tank . Let's find out:

The fish tank is in the shape of cuboid , and we know that volume of cuboid :

⇒ [tex]Volume = length(width)(height)[/tex]

Now , according to question we have following parameters :

[tex]V=910ml=910cm^3\\w=7cm\\h=10cm[/tex]

Therefore , Putting theses values in above equation we get :

⇒ [tex]Volume = length(width)(height)[/tex]

⇒ [tex]910 = length(7)(10)[/tex]

⇒ [tex]910 = length(70)[/tex]

⇒ [tex]length=13cm[/tex]

Therefore , the length of the fish tank is  [tex]length=13cm[/tex] . Correct option is A)

Option A) 13 cm is the length of the fish tank.

Step-by-step explanation:

Peter has just purchased a small rectangular fish tank that holds 910 milliliters of water.

(1 milliliter is equal to 1 cubic centimeter)

⇒ Volume of the fish tank = 910 cubic centimeter

  • The width of the tank = 7 cm
  • The height of the tank = 10 cm
  • The length of the fish tank = x cm

We know that, Volume of a cuboid = length × width × height

⇒ 910 = x × 7 × 10

⇒ 910 = 70x

⇒ x = 910 / 70

⇒ x = 13 cm

Therefore, Option A) 13 cm is the length of the fish tank.
