Question

Find the volume of a cube whose surface area is 486

Answer 1

$<I>$☞HEYA MATE☜



★ VOLUME OF A CUBE = a³


Edge = a 
Surface area = 6a² = 486 cm² 

6a² = 486 cm² 

a² = 486 /6 

a² = 81 

a = √81 

a = 9 cm 

Edge = a = 9 cm

Volume = a³ = 9³ = 729 cm³

Answer 2

TSA of a cube = 6a SQ
486= 6a SQ
81= a square
9 = a

therefore the volume of cube = a cube
