3D Shapes (8) Flashcards
Volume =
Area of a shape you know x the 3rd dimension
Unwrapping a cylinder
A rectangle. The distance around the circle is the circumference, which will give you your length x the height equaling the area
Greatest distance from point to point…
A hypotenouse between the two corners
Cube Surface Area formula…
6x^2
Unless a shape is perfectly symmetrical (cube, sphere)…
There is no concrete relationship between volume and surface area
Volume of a rectangle…
Length x width x height
Greatest distance in a box (or cube)…
SQRT of l^2 + w^2 + h^2
Volume of a cube…
x^3
Cylinder volume and surface area formulas…
V = area of circle x height of cylinder; SA = area of circle x 2 + area of rectangle formed by height of cylinder and circumference of circle
Rectangular box volume and surface area formulas…
volume = l x w x h SA = add surface areas of all 6 sides
Greatest possible distance in a cube…
s sqrt 3
