96 square units.
A rectangular box that is 6 by 8 by 12 units has a surface area of 2 x (6 x 8) + 2 x (6 x 12) + 2 x (8 x 12) = 432 square units
12 × 8 × 9.6 = 921.6ft3 (921.6 cubic feet).* * * * *That is the volume! The surface area is2*(12*8 + 8*9.6 + 9.6*12) = 576 square feet.
Floor area = ceiling area = 11 x 8 = 88 sq feet Wall area = 2 x 11 x 12 + 2 x 8 x 12 = (22 + 16) x 12 = 38 x 12 = 456 sq feet

8" x 12" = 96 square inches
Area = 1/2 x sum_of_lengths_of_parallel_sides x distance_between_themIf 14 in and 12 in are the parallel sides and 8 in is the distance between them:Area = 1/2 x (14 in + 12 in) x 8 in = 104 in2If 14 in and 8 in are the parallel sides and 12 in is the distance between them:Area = 1/2 x (14 in + 8 in) x 12 in = 132 in2If 12 in and 8 in are the parallel sides and 14 in is the distance between them:Area = 1/2 x (12 in + 8 in) x 14 in = 140 in2
Area = 1/2 (sum of bases) times height Area = (8+12)/2 x 4 Area = 10 x 4 = 40
Assuming the base is square, then: The area of the two bases = 2 x 8 x 8 = 128 cm The area of the four side areas = 4 x 8 x 12 = 384 cm Total area = 128 + 384 = 512 cm
8 x 3.5 = 28 square inches
96 square feet The total area is 8*12 or 96 square feet
