GIVEN:
A cube of side 12 cm
SOLUTION:
Total surface area of a cube = 6a², (where a = length of one side)
==> TSA = 6(12)²
= 6 × 144
= 864
∴Required TSA of cube = 864 cm² ✅

As a note:
If you find it hard to remember the formulas, just understand the relationship between areas and the sides of a prism,
I.e, Volume = Base area × height
LSA = Base perimeter × height
TSA = 2 Base area × height
If you know this then you don't have to mug up the formulas ✌☺
