314 square inches in total
a^2 + b^2 = c^2. Therefore, the hypotenuse is (5^2 + 12^2)^1/2
The scale of the house is the ratio of the model to the actual house. This ratio will be the same for both directions, or else the model would be useless. 6 inches is .5 feet, so the ratio is .5:30. You always want to write ratios as 1:something, so we double both side of the ratio and get 1:60. Likewise, 12 inches is one foot, so the ratio is 1:60 for the other dimension as well, as it should be.
Density is mass divided by volume. A brick is a rectangular prism, the volume of which is length * height * width. 7000 grams / (4 * 5 * 3) = 7000 / 60j = 116 2/3 g/cubic inch
5x5x6=150 If the cube has 5 inch long sides then each side has an area of 5 inches x 5 inches which equals 25 sqare inches. The cube has 6 sides so the total area of paper needed to cover it is 25 square inches x 6, which is 150 square inches of paper.

The volume is 12*6*5 = 360 cubic inches.The volume is 12*6*5 = 360 cubic inches.The volume is 12*6*5 = 360 cubic inches.The volume is 12*6*5 = 360 cubic inches.
If the three measures refer to the lengths of the sides of a cuboid - and there is absolutely nothing in the question to justify such an assumption -Vol = 5*24*12 = 1440 cubic inches.
It will be 3375 cubic inches.
If 3 5 inches meant 35 inches, then the cube's volume is 35 x 35 x 35 = 42875 cubic inches.

The area of a triangle is (base*height)/2. Assuming 5 inches and 12 inches are the base and height (either order), the area is 5*12/2=30 square inches.
It's volume will be 12 000 cubic inches...
12x8x5=480 6x10x3=180 480-180=380
60*36*4 = 8640 in3 (cubic inches) = 5 ft3 (cubic feet)
