Question

If x = 8 units, y = 16 units, and z = 7 units, then what is the surface area of the rectangular prism shown above

Answer 1

Answer:a rectangular prism is actually a cuboid,which has six rectangular faces.We have to add the area of six faces to fins it's surface area.Let  length be labelled as (L),Width as (W) and Height as (H).Formula for surface area is  2lw+2lh+2hw

Step-by-step explanation:Let x be length =8 units,y be width =16 units and z be height =7 units.

Surface area=2lw+2lh+2hw

(2*8*16)+(2*8*7)+(2*16*7)

(2*128)+(2*56)+(2*112)

256+112+224

=592 square units.
