Determine the surface area of the rectangular prism below. 80 cm 2

100 cm 2

160 cm 2

17 cm 2

Determine the surface area of the rectangular prism below.

Length = 10cm

Width = 5cm

Height = 2cm

a) 80 cm²

b) 100 cm²

c) 160 cm²

d) 17 cm²

c) 160 cm²

Step-by-step explanation:

The formula for the Surface Area of a rectangular prism =

A=2(wl + hl + hw)

Length = 10cm

Width = 5cm

Height = 2cm

Hence:

Area =2× (5 × 10 + 2 × 10 + 2 × 5) cm²

= 2 × ( 50 + 20 + 10) cm²

= 2 × (80) cm²

= 160 cm²

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
