The surface area of a rectangular prism (a box shape) with a volume of 12 cubic units depends on the length of the sides. Using only integer lengths you can have any of the following:
(A) 1x1x12
(B) 1x2x6
(C) 1x3x4
(D) 2x2x3
The surface area of any of these is found by adding the area of each of the six faces with the equation: 2 * (A*B + A*C + B*C)
(A) 2 * (1*1 + 1*12 + 1*12) = 50
(B) 2 * (1*2 + 1*6 + 2*6) = 40
(C) 2 * (1*3 + 1*4 + 3*4) = 38
(D) 2 * (2*2 + 2*3 + 2*3) = 32

Is the area of a solid figure is the mearsure of the number of cubic units?
No, volume is in cubic units, while surface area is in square units.
Calculate cubic units in a rectangle?
A rectangle has a perimeter with linear units, and a surface area with square units. It has no cubic units.
What is the square units in a interior of a 2d figure or the surface of a 3d figure?
A 2D interior will be length times width (a flat shape) as in the area of a floor.A 3D figure would be length times width times depth (a raised shape) as in a box.The units used would depend. A floor would be in feet and inches or metres and centimetres.A 3D figure would be in a similar measurement, but given in cubic 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
What is the formulae for volume and surface area of cube?
For a cube with sides of x lnear units, volume = x3 cubic units.surface area = 6x2 square units.For a cube with sides of x lnear units, volume = x3 cubic units.surface area = 6x2 square units.For a cube with sides of x lnear units, volume = x3 cubic units.surface area = 6x2 square units.For a cube with sides of x lnear units, volume = x3 cubic units.surface area = 6x2 square units.
