Question

Find the surface area of each figure. Round your answers to the nearest tenth, if necessary. Pls help!!!!!

Answer 1

9)376ft^2 10)132ft^2

Explanation:

the first one is pretty easy use the formula 2(l*w+l*b+w*b) where l is length b is breadth and w is the width, l=10 b=8 w=6

2(10*6+10*8+6*8)

=376ft^2

the second one is also not that hard, first find out the area of the triangles in which the base is 3 and height is 4 so 4*3/2

=6

since there are two triangles, the surface area of the triangles combined is 12

now lets move the base where the width is 3 and the length is 10 as it also corresponds, now l*w is the formula to find the surface area of a rectangle so 10*3 is 30 now lets find the surface area of the square on the front which is just 10*5 which equals to 50 and lastly the rectangle at the back, for which we know that the width is 4 and length is 10 so 10*4 is 40 now simply just add all ofn these areas, 12+50+40+30

=132ft^2

Answer 2

376, and 122

Explanation:

To solve for the surface area, we add up the areas for each side together.

([8×6] × 2) + ([8×10] × 2) + ([10×6] × 2) = 376

376 is the surface area for the 1st shape.

(10 × 5) + (4×3) + ([3×10] ×2)= 122

122 is the surface area for the 2nd shape
