Question

hardest exercise in the world bet u wont solve it lol...........................................................................................................................................................................................................................................................What is the lateral area of a rectangular prism if the base edges are 3 centimeters and 4 centimeters and the height is 6 centimeters?

92 cm2

150 cm2

220 cm2

84 cm2

Answer 1

la=2h(w+l)

Answer 2

84 cm^2... the formula is 2h(l +b).... because the lateral surfaces are made up of four rectangles. Two of each are made up of (length and height ) and (base and height)...

So, total area = 2 l h + 2 b h = 2h(l+b)...

Now, put l= 3, b=4 and h=6 .. and get the answer.

Answer 3

ok

Answer 4

so i put l= 3, b=4 and h=6 but how do i solve it

Answer 5

multiply diivide?

Answer 6

this is ast qustion to finish the exam

Answer 7

anyone?

Answer 8

you have 4 lateral faces two of them are 3cm by 6 cm = 18 cm^2 for a partial area of 36 cm^2

the other two faces are 4cm by 6cm = 24 cm^2 for a partial area of 48 cm^2

adding the partial areas you have 48 cm^2 + 36 cm^2 = 84 cm^2
