Answer:
400 in²
Step-by-step explanation:
(20×16) + (½×8×20)
320 + 80 = 400 in²
Answer:
12*3/8 we just turn the 12 into a improper fraction and multiply the top and the bottom with 3/8 top and bottom so
12/1*3/8
12*3=36
1*8=8
so 36/8 the answer is
D
Hope This Helps!!!
I can help if you want me to
Answe is B: 50
It needs to equal 180 so
100+30=130
180-130=50
Break it down into 2-Dimensional shapes. Then add the areas together.
From the picture you can see;
front & back rectangles are 2*(4 x 8) = 64 m²
2 side rectangles are 2*(4 x 12) = 56 m²
2 triangular front & back pieces are (1/2)*8*3 = 12 m²
2 roof rectangles are 2*(5 x 12) = 120 m²
total Surface area = 64 m² + 56 m² + 12 m² + 120 m²
= 252 m²
For the volume; break it up into 3-dimenssional shapes and add the volumes together.
From the picture you can see;
Rectangular box volume is 4 x 8 x 12 = 384 m³
Triangular roof volume is area of front triangle multiplied through the length. (1/2)*8*3* 12 = 144 m³
Total volume = 384 m³ + 144 m³
= 528 m³
