V cuboid = L x l x h
At = 2 x (L x l + L x h + l x h)
V = 6 x 8 x 10 = 480dm³
A = 2 x ( 6 x 8 + 6 x 10 + 8 x 10) = 2 x (48 + 60 + 80) = 2 x 188 = 376 dm²
At = 2 x (L x l + L x h + l x h)
V = 6 x 8 x 10 = 480dm³
A = 2 x ( 6 x 8 + 6 x 10 + 8 x 10) = 2 x (48 + 60 + 80) = 2 x 188 = 376 dm²
v=lxLxh=6x8x10=480 dm3
a=2(Lxl+Lxh+lxh)=2(6x8+6x1-+8x10)=2x188=376 dm2
