Question

the total surface area of cube is 150 cubic cm . the area of the vertical faces of this cube is ​

Answer 1

Answer:

Step-by-step explanation:

Given:

Total surface area of a cube= 150 cm²

Total surface area of a cube= 6a²

[ a= side of a cube]

150 = 6a²

a²= 150/6

a²= 25

a= √25

a= √5×5

a= 5 cm

Volume of a cube= a³

Volume of a cube= 5³

Volume of a cube=5×5×5= 125

Hence, the Volume of a cube= 125 cm³

Answer 2

surface area of cube = 150 cubic cm.
=> 6a^2 = 150 cubic cm
=> a^2 = 150 ÷ 6
=> a^2 = 25
=> a = √25
=> a = 5 cm
Therefore, Area of cube a^3 = 5^3
= 5 × 5 × 5 = 25 × 5 cubic cm. = 125 cubic cm .{ Answer}
