Answer:
Height h = 9 cm
Step-by-step explanation:
Given:
Surface area of cuboid = 102 cm²
Length l = 2 cm
Breadth b = 3 cm
Find:
Height h
Computation:
Surface area of cuboid = 2[lb + bh + hl]
102 = 2[(2)(3) + (3)(h) + (h)(2)]
51 = 6 + 3h + 2h
45 = 5h
Height h = 9 cm
Answer: Area is 426
Step-by-step explanation: Do 15 x 26 which is 390 to find out the rectangle part, and the area for a triangle is 1/2 (b x h) so 9 x 8 is 72 and then divide by 2 is 36 so 390 + 36 is 426
