Question

if the total surface of a cube is 1014 sq cm find the lateral surface and main diagonal of the cube
​

Answer 1

Step-by-step explanation:

6a²=1014

a²=169

a=13

LSA=4a²=4(13)²=4×169=676 sq cm

Diagonal of cube =

$\sqrt{3} \: a$

$\sqrt{3} \: \: 13$

$13 \:\sqrt{3}$

Answer 2

Answer:

676 cm^2. 13√3 cm

Step-by-step explanation:

given total surface area cube 1014 cm^2

since we known that

total surfacearea of cube. 6 a^2
