hold on

Answer 2

okay, thanks @Sydthesquirrel

Answer 3

F

Answer 4

wait dont do it yet i messed up

Answer 5

\[V= 21*13*6 \]\[S= 2*( (21*13)+(21*6)+(13*6) ) \]

Answer 6

after you do that lemme show you how do to the next step

Answer 7

I'm going to label
L = Length (13)
W = Width (21)
H = Height (6)

Surface Area
S.A. = 2LW + 2LH + 2WH
S.A. = 2 (13)(21) + 2(13)(6) + 2(21)(6)
S.A. = 546 + 156 + 252
S.A. = 954 square units

Volume
V = L x W x H
V = 13 x 21 x 6
V = 1,638 cubic units

It's very important to have units!
