Question

Find the length of edge of a cube with following
surface area:
(1) 1944 cm
(ii) 2646 cm​

Answer 1

Answer:

BOTH THE ANSWERS ARE FOUND USING THE FORMULA TSA=6l^2

FOR THE FIRST ONE LENGTH OF EDGE IS 18 CM

FOR THE SECOND ONE LENGTH OF EDGE IS 21 CM

mark my answer as brainliest

Answer 2

surface area =6a^2

1) 1944 =6a^2

1944/6=a^2

324 =a^2

√(324=a

18=a

2)2646=6a^2

2646/6=a^2

441 =a^2

√(441=a

21=a
