Question

10 Three cubes are joined end to end forming a cuboid. If side of a cube is 3cm, then find the TSA and LSA of cuboid so formed. ​

Answer 1

TSA IS 130 CM SQUARE,LSA IS 81CM SQUARE

JOINING 3 cubes we obtain dimensions are

L=9CM

B=3CM

H=3CM

SO LSA OF CUBIOD IS L×B×H

9×3×3=81CM SQUARE

TSA OF CUBIOD IS 2(LB+BH+HL)

2(9×3+3×3+3×9)

we obtain 130CM SQUARE
