Question

a cuboid whose Total surface area is 50 m² And curved surface area is 30² find area of base

Answer 1

Total surface area = 50 m² (Given)

Total Surface area = 2 x base area + curved surface area

2 x base area + 30 = 50

2 x base area = 50 - 30

2 x base area = 20

base area = 20 ÷ 2 = 10 m²

Answer: Base area = 10 m²

Answer 2

HELLO FRIEND HERE IS YOUR ANSWER,,,,,,

A Cuboid of Total Surface are is

= 50 ${m}^2$

The formula for Total Surface area of a Given Cuboidal Surface

= 2 × Area of Base + Total Curved Surface Area

By substituting the given values of Total Surface area of Cuboid and Total Curved Surface Area,,, we get ,,,,

$= > 50 \: {m}^{2} = 2 \times Area \: \: Of \: \: Base \: + 30 \: {m}^{2} \\ \\ = > 50 \: {m}^{2} - 30 \: {m}^{2} = 2 \times Area \: \: Of \: \: Base \\ \\ = > 20 \: {m}^{2} = 2 \times \: Area \: \: Of \: \: Base \\ \\ = > \frac{20 \: {m}^{2} }{2 \: {m}^{2} } = Area \: \: Of \: \: Base \\ \\ = > Area \: \: Of \: \: Base \: = \: 10 \: {m}^{2}$

Which is the required solution for this type of query.
