➡ For solving these type of questions, first we have to know about all the formulas.
➡ Keeping in mind all the formulas, we can proceed as under :
❄SOLUTION TO ABOVE QUESTION :
Let the length be 'l', breadth be 'b' and height be 'h'.
So, Total surface area of cuboid
= 2(lb+bh+lh) square units
= 2{(4×2)+(2×2.4)+(2.4×4)} cm²
= 2 {8+4.8+9.6} cm²
= (2× 22.4) cm² (Ans.)
= 44.8 cm²
