To measure the volumes we need to know the measure 3 sides. Since volume involves 3 sides it is measured in cubic units. Volume of a cuboid = (length × breadth × height) cubic units. = (l × b × h) cubic units.

## What is the formula of volume of a cube?

Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.

## What is the formula of area of cuboid?

A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

## How do you find the volume of a 3D rectangle?

A rectangular prism is a 3D figure with 6 rectangular faces. To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

## What is the volume of a 3D object?

In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.

## How do you find the capacity of a rectangle?

Rectangular Containers You find the volume V of a rectangular container by measuring its length (l), width (w) and height (h) and multiplying these quantities. You express the result in cubic units.

## How do you calculate volume of a water tank?

For a rectangular tank: To find the capacity of a rectangular or square tank: Multiply length (L) by width (W) to get area (A). Multiply area by height (H) to get volume (V). Multiply volume by 7.48 gallons per cubic foot to get capacity (C).
