Find the surface area of the composite figure. 7 cm
10 cm
6 cm
7 cm
8 cm
2 cm

273.62 cm^2

Step-by-step explanation:

so surface area of a rectangular prism is 7*6 7*2 and 6*2 (this can be used with different numbers, i dont know how to explain it well) this would come out to 68

the trangular prism doesnt have a direct formula, but there are calculators on the internet you can look up, but it would come out to 205.62,

add the numbers together and you would get 273.62cm^2

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
