Step-by-step explanation:
=15.7/4
Answer:
Perimeter 18.8
area 15
Step-by-step explanation:
Use pythageriums theorem
6^2 + 5^2 = c^2
I found the sides by counting squares
6^2 + 5^2 = 61
square root it to find the answer
7.8 is the missing side so now add it all together
7.8+6+5= 18.8
to find the area do 6 x 5/ 2
so the answer is 15
Answer:
Step-by-step explanation:
A 3D figure is given to us and we need to find the Total Surface area of the 3D figure . So ,
From the cuboid we can see that there are 5 squares in one row on the front face . And there are two rows. So the number of squares on the front face will be 5*2 = 10 .
We know the area of square as ,
Hence the area of 10 squares will be 10x² , where x is the side length of each square. Similarly there are 10 squares at the back . Hence their area will be 10x² .
Also there are in total 12 squares sideways 6 on each sides . So their surface area will be 12x² . Hence the total surface area in terms of side of square will be ,
Now let's find out the TSA in terms of side . So here the lenght of the cuboid is equal to the sum of one of the sides of 5 squares .
Hence the TSA of cuboid in terms of lenght and breadth is :-
