Question

2
the total surface area of a cube whose volume is 343 cm3​

Answer 1

Answer:

6a square= TSA of cube

a cube= volume of cube

So,cube root of 343 is value of a.

then,a=7

thus,6×7×7=294cm2

Hence total surface area of cube whose volume is 343cm3 is 294cm2

Answer 2

Volume of cube s×s×s

=343cmcube

S= cube root of 343

=7cm

Total surface area=6×(s)square

=6×(7)square

=6×49

=294 cm square
