A=-.25+6.7t, s=.75+4.5t when Amir catches up a=s so:

-.25+6.7t=.75+4.5t add .25 to both sides

6.7t=1+4.5t subtract 4.5t from both sides

2.2t=1 divide both sides by 2.2

t=10/22 hr

t≈0.45 hr (to nearest hundredth)

Answer:

Total surface area of the prism =145.32 Square centimeters

Step-by-step explanation:

The given figure is a rectangular prism with the given dimensions of :

length(L)= 10.3 cm

Width(W)=2.2 cm

Height(H)=4 cm

Total surface area of the rectangular prism is:

$= 2(L*W+W*H+H*L)\\\\=2((10.3*2.2)+(2.2*4)+(4*10.3))\\\\=2(22.66+8.8+41.2)\\\\=2(72.66)\\\\=145.32cm^2\\\\$

Total surface area of the prism is 145.32 Square centimeters
