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

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
