A 3-dimensional object (NOT figure) is measurement in Cubic Units).
Its surface area is measuremd in Square Units.
For example if we use an house brick . Its dimensions may be 9inches, x 4 inches, x 3 inches.
Its volume is 9 ins X 4 ins X 3 ins. = 108 cu.ins. (Cubic Inches).
Its surface are will have 6 faces. ; 2 @ (9 x 4) 2 @ ( 4 x 3 ) and 2 @ (9 x 3)
So its surface area is 2(36 sq.ins) + 2(12sq. ins) + 2(27sq.ins) =
72 + 24 + 54 = 150 sq. ins. ( square inches).
NB A 3-dimensional is an OBJECT
A 2-dimensional us a FIGURE .
A 1-dimensional is a LINE

Why are square units used when working with a three-dimensional figure?
Surface area of three dimensional figures are measured in square units whereas their volumes are measured in cubic units
When measuring the amount of space in a three-dimensional figure you are finding what?
Its volume measured in cubic units.
Why is a solid figure measured in cubic units?
The length, width, or height of a solid figure is measured in units of length. The area of the figure's outside surfaces is measured in squared units of length. The volume of space filled by the figure is measured in cubed units of length. The mass of the figure is measured in units of mass. The weight of the object is measured in units of force. The age of the figure is measured in units of time. etc.
How to figure out the area of a sphere?
Surface area of a sphere = 4*pi*radius2 and measured in square units
What volume of rectangle objects?
A rectangle does not have volume because it is 2 dimensional but it does have area which is length times width measured in square units.
Why are square units used when working with a three-dimensional figure?
Surface area of three dimensional figures are measured in square units whereas their volumes are measured in cubic units
Why surface area is measured in square units even though the figure is three dimensional?
because you are just measuring the outside faces, therefore it is only measured in square units
What is square units to measure?
The area of a 3 dimensional figure
Are rectangles measured in cubic units?
no, cubic units are for three dimensional figures, hence cubic = 3 they are measured in square units, as they have only two dimensions.
When measuring the amount of space in a three-dimensional figure you are finding what?
Its volume measured in cubic units.
Why is surface aree measured by square units and volume is measured in cubic units?
Surface area is two-dimensional. Volume has a third dimension: depth.
Why is surface area measured in square units not cubic units?
Surface area is a two-dimensional measurement that only accounts for the external dimensions of an object, so it is measured in square units (e.g., square meters, square inches). In contrast, volume is a three-dimensional measurement that represents the space occupied by an object, so it is measured in cubic units (e.g., cubic meters, cubic inches).
Why is a solid figure measured in cubic units?
The length, width, or height of a solid figure is measured in units of length. The area of the figure's outside surfaces is measured in squared units of length. The volume of space filled by the figure is measured in cubed units of length. The mass of the figure is measured in units of mass. The weight of the object is measured in units of force. The age of the figure is measured in units of time. etc.
What is area mesured in?
Area is typically measured in square units such as square meters (m²), square feet (ft²), or square centimeters (cm²). It represents the amount of space occupied by a two-dimensional shape or surface.
Why is perimeter measured in linear units?
Perimeter is measured in Linear Units because it is Measurement of The Outline or Path of a given shape or area; a Perimeter is NOT the Measurement of What is Inside that Outline/Path. It is a One-Dimensional measurement, which MEANS it is a Linear Unit Measurement, such as Feet or Meters.Alternatively, a Two-Dimensional Measurement, is the Square of a Linear Unit -- like AREA is a Two-Dimensional Measurement and therefore Measured in Linear Units Squared (i.e. meters2/Square Meters or feet2/Square Feet). Area is the Measurement of What is Contained within a given Perimeter.
How to figure out the area of a sphere?
Surface area of a sphere = 4*pi*radius2 and measured in square units
What does area units measure?
Area units measure the amount of space that a two-dimensional shape covers. It is typically expressed in square units, such as square meters, square feet, or square centimeters. The larger the value of the area unit, the greater the space occupied by the shape.
