Answer:
330cm³
Step-by-step explanation:
calculate the from surfacr and then multiple it with 6cm
the rectangle in the from is 3cm*10cm= 30cm²
the triangle got a base of 10cm and a height of 5cm. we can know that because of the 45° angle. imagine two smaller triangles here (see my wacky drawing attempt)
anyways, that gives us 25cm² for the big triangle.
making the front 55cm² in total
multiplied with 6cm it's 330cm³
