Question

math

Answer 1

there are total 6 rectangles
do you know formula for area of a rectangle ?

Answer 2

what is this 27 ?

Answer 3

ok wrong but i forgot the formula

Answer 4

So, the surface area equation my teacher taught me was, \(SA=2B+Ph\)

B = \(l \times w\)
P = \(2l+2w\)

now we plug these in, so

B = \(12 \times 6\) = \(72in^2\)
P = \(2(12)+2(6)\) = \(36in^2\)

now we plug these into the equation \(SA=2B+Ph\) and add in the height

\(SA=2(72)+36(3)\)
which gives you
\(252in^2\)

Answer 5

Surface area for ALL prisms, not just rectangular prisms.

Answer 6

so 252
