10 cubes each of edge 1 cm long are placed together. Find the total surface area of the cuboid so formed
Please answer
Answers
Given that
Edge of a cube = 1 cm
Number of cubes are given = 10
If 10 cubes of each 1 cm are placed together i.e. they are joined end to end then the resultant solid is a cuboid.
Length of the cuboid (l) = 10 cm
Since length = 10× edge of cube = 10×1 = 10 cm
Breadth of the cuboid (b) = 1 cm
Height of the cuboid (h) = 1 cm
We know that
Total surface area of a cuboid
TSA = 2(lb+bh+hl) sq.units
Total Surface Area of the given cuboid
= 2[(10×1)+(1×1)+(1×10)] cm²
= 2(10+1+10) cm²
= 2(21) cm²
= 42 cm²
Total Surface Area = 42 cm²
Answer:-
Total Surface Area of the resultant cuboid is 42 cm²
Used formulae:-
→ Total surface area of a cuboid
TSA = 2(lb+bh+hl) sq.units
l = lengthb = breadthh = heightUsed Concept :-
→ If cubes are joined by end to end then the resultant solid is cuboid .
