Question

f) Find the surface area of a cube with side length is 1.7 m.​

Answer 1

Answer:

TSA = 17.34 m²

LSA = 11.56 m²

Step-by-step explanation:

Total surface of a cube =  6a² sq.units, where a is the side of the cube

here, a = 1.7m

=> TSA of the cube =  6*1.7m*1.7m

                                =  6*2.89 m²

                                =  17.34 m²

also, LSA, lateral surface area = 4a² sq.units

                                                   = 4*1.7m*1.7m

                                                   = 4*2.89 m²

                                                   = 11.56 m²

Answer 2

Answer:

17.34 Sq m

Step-by-step explanation:

First we find area of single side that will be 1.7x1.7

which is 2.89 Sq.m

And then multiply it by 6 as all faces of a cube are same.
