ROCK FALL game to practice
'Calculate surface area of cuboids' for 8th grade

Calculate the surface area of cuboids

The surface area of a cuboid such as a rectangle is the sum of the areas of each of it's six sides.

Since each pair of opposite sides have the same area, we can sum the areas of the 3 sides LW LH and WH (where L = length, W = width and H = height) and then double that value.

So a general formula for calculating the surface area of cuboids is:

SA = 2LW + 2LH + 2WH

or

SA = 2(LW + LH + WH)

With our Rock fall math game you will be practicing the topic "Calculate surface area of cuboids" from 8th grade / Geometry & measures / Measures of 3D shapes / Measures of 3D shapes. The math in this game consists of 16 questions that ask you to calculate the surface area of cuboids using the formula SA =2(LW+LH+HW).

Large thumbnail for math game Rock fall

ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.

There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
