the total surface area of a cube is 294 dm2 what is the volume

Sagot :

Surface area of cube = 6a²

Given surface area = 294 dm²

6a² = 294 dm²

6a² = 294 dm² 
 6           6

a² = 49 dm²

√a² = √49 dm²

a = 7 dm (side of a cube)

VOLUME OF CUBE = side ³

V = (7 dm)³    or   V = (7dm) (7 dm) (7dm)
V =  343 dm³
