Question

the lateral surface area of a cube 324cm2 find volume FSA

step by step plz ​

Answer 1

Answer:

∴ Lateral surface area of the cubical box = 4a2 = 4(10)2 = 400 cm2. = 2(12.5+ 10)(8) = 360 cm2.

Answer 2

Answer:

Let each side of the cube be

a

cm <br> then, the lateral surface area of the cube

= (4a^(2)) cm^(2)

<br>

:. 4a^(2) = 324 rArr a^(2) = 81 rArr a = sqrt81 = 9

<br> Volume of the cube

= a^(3) cm^(3)

<br>

= (9 xx 9 xx 9) cm^(3) = 729 cm^(3)

<br> Total surface area of the cube

= (6a^(2))

sq units <br>

= (6 xx 9 xx 9) cm^(2) = 486 cm^(2)
