The diagram shows a cuboid.
8 cm
15 cm
20 cm
What is the surface area of the cuboid?

surface area of the cuboid = 1160

Step-by-step explanation:

surface area of a cuboid = 2 ( lb + bh + lh )

( where, l = length, b = width, h = height )

so, surface area =

=》2 ( (8 × 15) + (15 × 20) + (20 × 8) )

=》2 ( 120 + 300 + 160 )

=》2 × 580

=》1160

so, surface area = 1160 sq.cm

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
