A roof of the house including its base is in the shape of right prism with a triangular base with the dimensions shown.
What is the approximate surface area of this prism?

391.2cm²

Step-by-step explanation:

Triangle = 1/2bh*2=1/2(4)(6.9)(2)=27.6 for each end triangle.

14*8=112 for each rectangular side.

112+112+112+27.6+27.6=391.2cm²

step-by-step explanation:

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
