3D Shapes

Surface areas and volume of 3D shapes

2πr circumference of a circle
1/2 d1d2 area of a rhombus
πr² area of a circle
area of a square
1/2 ap area of a regular polygon
h(b1+b2)/2 area of a trapezoid
Ph lateral area of prism
La+2B Total area of a prism
Bh volume of prism
6e² total area of a cube
volume of a cube
1/2 Pl surface area of a pyramid
LA+B total area of a pyramid
1/3 Bh volume of a pyramid
Ch Lateral area of cylinder
LA+2B Total Area of a cylinder
Bh volume of cylinder
1/2Cl Lateral Area of a Cone
LA+B total area of a cone
1/3Bh volume of a cone
4/3 πr³ volume of a sphere
a²+h²=l² slant height
Cube SA = 6(e squared) V = e cubed
Rectangular Prism SA = 2(lw + wh + lh) V = Bh
Prism SA = Sum of the Area of the Bases OR Perimeter of the base times the height + area of two bases V = Bh
Cylinder SA = 2pi(radius squared) + 2pi(rh) V = pir squaredh
Pyramid SA = Sum of the areas of the faces V = 1/3 Bh
Cone SA = pi*r (l+r) V = 1/3 pir squaredh
Sphere SA = 4pir squared V = 4/3 pi*r cubed



Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
