Algebraic Identities comprises of several equality equations which consist of different variables.
If a natural number, m = n2 and n is a natural number, then m is said to be a square number.
Numbers, when obtained while multiplied by itself three times, is known as cube numbers.
Discounts are the reduction value prevailed on the Marked Price (MP).
Overhead expenses are the additional expenses made after purchasing an item. These are included in the Cost Price (CP) of that particular item.
GST (Goods and Service Tax) is calculated on the supply of the goods.
Compound Interest (CI) is the interest which is compounded on the basis of the previous year’s amount.
Formula of Amount (Compounded Annually): \(A = P \left (1 + \frac{R}{100} \right )^t\)
P = Principal,
r = Rate of Interest, and
t = Time Period
Formula of Amount (Compounded Half Yearly): \(A = P \left (1 + \frac{R}{200} \right )^{2t}\)
R/2 = Half-yearly Rate,
2t = Number of Half-Years
Any useful information that can be utilized for some specific use is known as Data. These data can be represented either graphically (Pictograph/Bar Graph/Pie Charts) or symmetrically (Tabular form). Find the important Class 8 Maths formulas for Data Handling and Probability.
Probability = Number of Favourable Outcomes / Total Number of Outcomes
Here, we will define the geometrical formulas consistently used in Mathematics Class 8. We will use the following abbreviations for convenience:

Cube | LSA: 4a2 TSA: 6a2 Volume: a3 a = sides of a cube |
Right Pyramid | LSA: ½ × p × l TSA: LSA + Area of the base Volume: ⅓ × Area of the base × h p = perimeter of the base, l = slant height, h = height |
Right Circular Cylinder | LSA: 2(π × r × h) TSA: 2πr (r + h) Volume: π × r2 × h r = radius, h = height |
Right Circular Cone | LSA: πrl TSA: π × r × (r + l) Volume: ⅓ × (πr2h) r = radius, l = slant height, h = height |
Right Prism | LSA: p × h TSA: LSA × 2B Volume: B × h p = perimeter of the base, B = area of base, h = height |
Sphere | LSA: 4 × π × r2 TSA: 4 × π × r2 Volume: 4/3 × (πr3) r = radius |
Hemisphere | LSA: 2 × π × r2 TSA: 3 × π × r2 Volume: ⅔ × (πr3) r = radius |
