Question

find the total surface area of a geometry box of dimensions 10 cm , 5 cm and 3 cm
​

Answer 1

Answer:

Total surface area oof geometry box=190 cm sq

Answer 2

Answer:

190cm²

Step-by-step explanation:

Given, length = 10cm

breadth = 5cm

height = 3cm

we know that a geometry box is usually a cuboid

therefore, Total surface area of a cuboid

= 2lb + 2lh + 2hb

= [2(10)(5) + 2(10)(3) + 2(3)(5)]cm²

= [100 + 60 + 30]cm²

= 190cm²

Thus, the total surface area of the geometry box is 190cm²
