Question

calculate the surface area of each of the following geometrical shapes
Plss help me. I got 1093 cm2
But the actual answer is 1092 cm2. I need for revision
I will mark as brainliest answer

Answer 1

1092cm².

Answer:

Solution given:

First Side (a)= 18cm

Second side (b)=8cm

length(l)=15cm

height(h)=12cm

slant height (c and d)=13cm

Now we have

Total surface area of the trapezoid prism

=2 × area of base + lateral surface area

=2*area of trapezoid +perimeter of trapezoid*length =2*½*h*(a+b)+(a+b+c+d)*l

=12(18+8)+(18+8+13+13)*15

=1092 cm^2

Total surface area of the trapezoid prism is 1092cm².
